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.

JavaScript Rest Parameters: Because Sometimes You Just Need More Args

Ever found yourself writing a function and thinking, “I don’t know how many arguments this will need… maybe 2, maybe 20?” Well, JavaScript has your back with something called rest parameters.
They’re like a magic bag that scoops up all the leftover arguments into a neat array.

Pipelining might be my favorite programming language feature
Free-standing function call syntax considered kind of suboptimal.
https://herecomesthemoon.net/2025/04/pipelining/
Pipelining might be my favorite programming language feature.
What is pipelining?
Pipelining is the feature that allows you to omit a single argument from your parameter list, by instead passing the previous value.

Contract-as-Code: Why Finance Teams Are Taking Over Your API Contracts
DevOps teams face growing friction from outdated contract workflows.
https://thenewstack.io/contract-as-code-why-finance-teams-are-taking-over-your-api-contracts/
In cloud native environments, we often discuss how contracts between microservices define stable interfaces and explicit dependencies. However, there’s another type of contract that’s just as critical but rarely gets the same developer attention: business agreements. As the founder of Concord, I’ve observed how enterprises managing thousands of vendor relationships struggle to integrate these human contracts into their automated workflows, creating significant bottlenecks for DevOps teams.
Organizations adopting Kubernetes and containerized architectures create elegant systems in which services communicate through well-defined APIs. Teams write contracts for these interactions, ensuring stable interfaces as individual components evolve independently.
Yet many DevOps teams are discovering a hidden technical debt: the business contracts governing these same systems aren’t integrated into their automation pipelines. Research from World Commerce & Contracting indicates organizations lose an average of 9.2% of contract value due to poor management processes.

New Linux Patches Aim To Customize Out-Of-Memory Behavior Using BPF
https://www.phoronix.com/news/Customize-Linux-OOM-Using-BPF
A fresh take is being pursued around allowing the Linux kernel’s out-of-memory (OOM) behavior to be customized using BPF programs.
Google engineer Roman Gushchin has sent out a “request for comments” patch series with a new take on allowing for OOM customization using BPF. There have been previous attempts at BPF-based OOM customization for adapting the kernel’s behavior but no solution yet ultimately deemed the best and suitable for upstreaming.
