Coding trends 2025

In the tech world, there is a constant flow of changes and keeping up with them means the choice for tools and technologies which are the most appropriate to invest your time in. In 2025 the best programming language or technology stack to learn really depends on your personal aims, hobbies, and apps you are going to create.

The interest in Java is dropping. February 2025 TIOBE programming community index. C++, which has long been the cornerstone of system programming and performance-critical applications, has officially overtaken Java to take second place in the TIOBE programming language popularity index. A new report from the Java vendor Azul claims that 88% of companies are considering moving off of Oracle Java to another alternative as a result of rising costs and restrictive policies from Oracle, among other issues.

The growing trend in the world of software development: speed matters. C++, Go, and Rust are gaining popularity because the need for computing power increases faster than speed of CPUs is increasing, sothere is a growing interest to the fast programming languages. While C++ is establishing itself, other fast languages ​​are making significant strides. Go continues its top 10 ranking, while Rust has reached an all-time high.

Python still holds its place at the top of the programming world. Since the number of trained experts in the software industry is not enough to cover the growing need, professionals from many other fields are taking over programming skills with the help of Python. This ensures that Python maintains its position even as speed continues to be emphasized in programming language choices. Programs written with Python are often notoriously slow and inefficient. Python 3.14, due out later this year, is set to receive a new type of interpreter that can boost performance by up to 30% with no changes to existing code.

Must-Know 2025 Developer’s Roadmap and Key Programming Trends article says that in the world of coding trends, one thing is clear: classic languages like Java, Python, and JavaScript are still important, but they’re being joined by new favorites such as Go and Rust. And when you ask “Is JavaScript or Python 2025?” the answer is rarely simple – and could be that you need both.
Here are some points:
Python’s Growth in Data Work and AI: Python continues to lead because of its easy-to-read style and the huge number of libraries available for tasks from data work to artificial intelligence. Tools like TensorFlow and PyTorch make it a must-have.
JavaScript and Its Ongoing Role in Building Website: JavaScript (and by extension, TypeScript) is the basic building block. JavaScript is still essential for web work, running both the parts you see on a site and the behind-the-scenes work, but many coders are now preferring TypeScript for business projects. Try building a small web app using React.
The Rise of Go and Rust: For those looking at future coding languages 2025, Go and Rust are getting a lot of attention.
Java, C++, and C#: The Reliable Favorites: Even in 2025, there’s no ignoring that languages like Java, C++, and C# are still important. Java continues to be a top choice for large business applications and Android app development, while C++ is key in systems work and game development.
There are several shifts that every aspiring coder should keep in mind:
Adding Artificial Intelligence to Coding: The future of coding is closely linked with AI
Building for the Cloud: With cloud computing becoming common, languages that handle many tasks at once and run fast (like Go and Rust) are more important than ever.
The Need for Full-Stack Skills: Coders today are expected to handle both the front part of websites and the back-end work. JavaScript, along with tools like Node.js and modern front-end libraries, is key.
Focus on Safety and Speed: With online security becoming a big issue, languages that help avoid mistakes are getting more attention. Rust’s features that prevent memory errors and Go’s straightforward style are good examples.
Keep Learning and Stay Flexible: One thing that never changes in tech is change itself. What is popular in 2024 might be different in 2025.

Here’s a simple table that sums up some facts in plain language:

Language 2025 Trend Main Advantage Resource Link
Python Leads in data work and AI Easy to read, lots of tools GeeksforGeeks
JavaScript Essential for building websites Works everywhere on the web Snappify
TypeScript Becoming popular in large projects Helps catch errors early Fullstack Academy
Go Growing quickly in cloud computing Fast and handles many tasks at once Nucamp
Rust New favorite for safe, low-level coding Prevents common memory mistakes The Ceres Group
Java Still important for big business and Android work Runs on many types of systems Wikipedia

What’s trending in Software-driven Automation (SDA) in 2025? Here are some predictions:
1. Virtual Safe Control – A new and novel concept introduced by CODESYS and SILista, making it possible to implement Functional Safety controller reaching SIL2 or even SIL3 level, using generic hardware with help of software virtualisation. This will significantly decrease cost of hardware and speed up development cycle.
2. Open platforms – This trend started already last year, and now we’re seeing more and more automation vendors coming this way. #ctrlXOS opened the game, and there are other vendors like Phoenix coming the same way with their PLCnext Virtualised.
3. Model-based Design (MBD) – An old concept but not yet fully utilised in development. Maybe because lack of well integrated toolchains in the past. But now we’re seeing more and more industrial players adopting the methodology in their product development.
4. AI, of course, but how? Naturally AI can assist in efficient software development and testing. Also some algorithm optimisation and condition monitoring with AI and ML has been seen.

    HTML’s Best Kept Secret: The Tag
    https://denodell.com/blog/html-best-kept-secret-output-tag

    Every developer knows . It’s the workhorse of the web.

    But ? Most have never touched it. Some don’t even know it exists.

    That’s a shame, because it solves something we’ve been cobbling together with s and ARIA for years: dynamic results that are announced to screen readers by default.

    It’s been in the spec for years. Yet it’s hiding in plain sight.

    Here’s what the HTML5 spec says:

    The element represents the result of a calculation performed by the application, or the result of a user action.

    It’s mapped to role=”status” in the accessibility tree. In plain terms, it announces its value when it changes, as if it already had aria-live=”polite” aria-atomic=”true”.

    In practice, that means updates do not interrupt the user. They are read shortly after, and the entire content is spoken rather than just the part that changed. You can override this behavior by setting your own ARIA properties if needed.

    Usage is straightforward:

    Your dynamic value goes here
    That’s it. Built-in assistive technology support. No attributes to memorize. Just HTML doing what it was always meant to do.

    A few things to know
    Like , has a for=”” attribute. Here you list the ids of any elements the result depends on, separated by spaces:

    +
    =

    For most users, nothing changes visually. But in the accessibility tree it creates a semantic link, letting assistive technology users connect the inputs with their calculated result.

    It doesn’t require a either. You can use it anywhere you are updating dynamic text on the page based on the user’s input.

    By default is inline, so you’ll usually want to style it for your layout, just as you would a or .

    And because it has been part of the spec since 2008, support is excellent across browsers and screen readers. It also plays nicely with any JavaScript framework you might be using, like React or Vue.

    Why Engineers Can’t Be Rational About Programming Languages
    https://spf13.com/p/the-hidden-conversation/

    The Leadership Blindspot: How Identity Drives Multi-Million Dollar Technical Debt
    A programming language is the single most expensive choice a company makes, yet we treat it like a technical debate. After watching this mistake bankrupt dozens of companies and hurt hundreds more, I’ve learned the uncomfortable truth: these decisions are rarely about technology. They’re about identity, emotion, and ego, and they’re destroying your velocity and budget in ways you can’t see until it’s too late.

    They pressured our CEO to recruit a CTO with more experience. I looked forward to learning from him; he was a well known figure in the Perl community and arrived with a stack of O’Reilly “camel” books.

    One of his first acts was to pronounce our language, PHP, the wrong choice. He decreed a switch to Perl. This decree happened after what felt to me like a sham analysis comparing PHP and Perl.

    Our velocity collapsed. Our team had to not only learn a new language but rebuild from scratch, delaying our product by nine months. Our monthly burn rate jumped from $200K to $500K as we more than doubled our size to make up for the lost velocity while building the new Perl based system, which halved our runway.

    Our CTO did deliver, at least on some of his promises. We built a beautiful system, one I was truly proud of. But it was too late. By the time we finally launched, the market opportunity had vanished. Facebook had now expanded beyond colleges, and we were at the end of our monitary runway.

    I’ve often wondered: What if we had just stuck with PHP? We had a fine system and real momentum. We would have launched much earlier at a fraction of the cost. PHP was good enough for Facebook; why not us?

    But the question that haunted me was: Why did such an experienced leader make such an terrible mistake?

    Promises Made

    Switching to Perl would unlock the architecture we needed
    Rebuilding from scratch would accelerate hiring and quality

    Reality Delivered

    Velocity collapsed as the team relearned and rebuilt everything
    Burn rate jumped from $200K to $500K per month
    The Pattern Repeats
    As my career progressed I saw this same pattern over and over.

    As Languages Product Lead at Google, my group included C++, Java, Go, and Python. At MongoDB, I managed teams writing in 13 different languages. In both places I saw brilliant engineers arguing past each other, armed with conflicting data, all of it true, but none of it complete. At Google Cloud, I saw these same challenges across our customers.

    Fast forward two decades from Takkle, and I had déjà vu. I watched as a VP of Engineering presented to leadership why his team needed to build their next system in Rust.

    Now, every single reason given for choosing Rust in this presentation, Go was objectively better at. As an example: they cited “easy build and deploy” as a Rust advantage. It’s true that this is a strength of Rust, but Go’s nearly instant cross compilation and single static binary is even stronger than Rust in this specic critera with Rust’s very long build times.

    I pulled the VP aside after the meeting. “Walk me through how you evaluated other language candidates,” I said. His face went blank. “We… didn’t really look at any others,” he admitted. “Everyone’s talking about Rust.” There it was: a 50 million dollar decision made on hype, about to be green lit.

    Every Technical Debate Is Really Two Conversations
    In every language discussion, two conversations are happening simultaneously.

    The Visible Conversation: “Rust has memory safety without garbage collection.” “Go has faster compile times and easier deployment.” “Python has the richest ML ecosystem.”

    The Invisible Conversation: “I am a Rust programmer.” “I want to become a Rust programmer.” “I cannot imagine being someone who doesn’t choose Rust.”

    Microsoft’s AI CEO explains why he wants employees in the office, working at open desks
    https://www.businessinsider.com/microsoft-ai-ceo-mustafa-suleyman-rto-offices-employees-open-desks-2025-11

    Microsoft AI CEO Mustafa Suleyman enforces strict in-person office work policies for his team.
    Suleyman requires at least four days in the office, exceeding Microsoft’s general three-day mandate.
    He has set up open office layouts to boost collaboration.

    Suleyman requires employees to work from the office more than is standard at the company and generally prefers to have open floor plans, a polarizing concept at Microsoft and in engineering in general.

    “I very much believe in the in-person working culture,” Suleyman told Business Insider. “We’ve been defragmenting our culture and trying to concentrate.”

    Microsoft recently announced a new return-to-office mandate requiring most employees to work in an office at least three days a week, starting January 26.

    In contrast, Suleyman requires at least four-days-a-week for his employees who live near an office, according to an internal document viewed by Business Insider. Any exceptions must be approved by an executive who reports to Suleyman directly.

    “Much better for collaboration,” Suleyman said. “Everyone can see everyone else who’s in. You can feel the buzz, like there’s a real intensity about the place, and it just creates a lot more, like informal collaboration. It’s so much better.”

    ‘Vibe coding’ named word of the year by Collins Dictionary
    https://www.bbc.com/news/articles/cpd2y053nleo

    If you’ve ever wanted to create your own computer program but never learnt how to code, you might try “vibe coding”.

    Collins Dictionary’s word of the year – which is confusingly made up of two words – is the art of making an app or website by describing it to artificial intelligence (AI) rather than by writing programming code manually.

    The term was coined in February by OpenAI co-founder Andrej Karpathy, who came up with the name to represent how AI can let some programmers “forget that the code even exists” and “give in to the vibes” while making a computer program.

    It was one of 10 words on a shortlist to reflect the mood, language and preoccupations of 2025.

    By giving an AI tool a simple description such as “make me a program that schedules my weekly meals”, people can use “vibe coding” to make basic apps without any previous programming knowledge.

    More complicated tools still require skill, but the practice has opened up creating digital platforms to non-coders.

    He joins tech leaders like Nvidia and Klarna CEOs in touting vibe coding tools like Cursor.

    “The bar to coding is now lower than it ever has been,” Ng said in a talk at Snowflake’s “Build” conference on Monday. “People that code, be it CEOs and marketers, recruiters, not just software engineers, will really get more done than ones that don’t.”

    Ng is a Stanford professor and the founder of Google Brain. He now runs several AI-focused businesses.

    Rust vs. Python: Finding the right balance between speed and simplicity
    https://blog.jetbrains.com/rust/2025/11/10/rust-vs-python-finding-the-right-balance-between-speed-and-simplicity/

    Deciding whether to use Python or Rust isn’t just a syntax choice; it’s a career bet. According to the StackOverflow Developer Survey, Python dominates in accessibility, with 66.4% of people learning to code choosing it as their entry point. Python usage skyrocketed from 32% in 2017 to 57% in 2024, making it the tool of choice for “more than half of the world’s programmers.” GitHub has also reported that Python overtook JavaScript as their most-used language for the first time in over a decade.

    But Rust’s trajectory tells a different story. Despite its complexity, its usage has grown from 7% to 11% since 2020. It’s also been the “Most Admired programming language” for nine straight years, with over 80% of developers wanting to continue using it.

    The real question isn’t which language will “win” – it’s which one positions you for the problems you want to solve. This article explores their syntax, performance, learning curves, type systems, memory management, concurrency, ecosystems, and tooling to help you make a decision that aligns with both market realities and your career goals.

    This comparison shows that Rust and Python are built for different needs and approaches. Modern software development increasingly reveals that their strengths work together rather than compete.

    Python remains excellent for rapid application development, data analysis, machine learning, and scripting, propelled by its accessible syntax, flexibility, and mature ecosystem. On the other hand, Rust is the best choice for performance-critical applications, systems programming, embedded development, and projects where memory safety and efficient concurrency are essential.

    If you’re trying to build reliable, high-performance systems with Rust or exploring the language professionally, JetBrains RustRover offers a minimally configured environment with deep language support. With a non-commercial license available for learners and hobbyists, it’s a superb tool to grow with as you delve into Rust.
