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:

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

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.

    Why is JWT popular?

    This is by far the best description of the pros cons and implications of JWT use and the different flavours that i have seen. Balanced simple and factual

    This is a good intro to JWTs. Although, I do think that JWT, oauth and oidc is being somewhat mixed together. JWT’s does not necessarily provide authorization or authentication. JWT is just a standard for signing JSON claims.

    Just say no to JavaScript
    opinion
    https://www.infoworld.com/article/3616471/just-say-no-to-javascript.html

    JavaScript gives you too many ways to shoot yourself in the foot. Just what you’d expect from a programming language that was created in a week.

    The JavaScript programming language has a lot of history, but it was created over about — yes — a week in 1995. It was first called LiveScript, but the name was changed to JavaScript to ride the bandwagon for Java, despite having nothing to do with Java. It soon became very popular, enabling the web application revolution and drawing support by practically every web browser on the planet. Today JavaScript may be the most commonly used programming language in the world.

    I’m not a fan.

    I’ve said for years that JavaScript is to the web browser what assembly code is to the CPU. Sure, assembly is a powerful language, just as JavaScript is, but we have higher-order languages for a reason. And given that the browser is the real operating system these days, JavaScript should — and eventually will — go the way of assembly in the minds of developers.

    I don’t deny JavaScript’s success and effectiveness. The web is built on it, and people have done amazing things with it despite its substantial shortcomings. But I just can’t bring myself to think of JavaScript as a language that we should be writing, just like only a precious few developers write assembly language today.

    I prefer having a compiler write my assembly language when building Windows applications, and I prefer having compiled TypeScript write my JavaScript for me when building web applications.

    TypeScript is another story. Now there is a programming language. Designed by the great Anders Hejlsberg, TypeScript has all of the benefits of JavaScript (such as they are) while adding a type system that is expressive and powerful. Frankly, I don’t understand why anyone would prefer JavaScript over TypeScript.

    Why don’t you use TypeScript?

    First, you can start with TypeScript at your own pace. It’s not all or nothing. All JavaScript code is TypeScript code. I (mostly) joke that I will be happy to charge a nice fee to convert all JavaScript development teams to TypeScript developers by simply changing all their *.js files to *.ts files. With that one change, they would become a TypeScript shop, and they wouldn’t have to change how they wrote code at all. They could then gradually start using TypeScript as they want.

    My lack of understanding further stems from the lame objections that developers make to using TypeScript.

    “JavaScript is great for quick prototypes”

    Okay, that’s fine, but consider this: We all know that the notion of a “prototype” is kind of a joke. It’s sadly rare when a prototype is tossed aside and the “real” application is started again. Prototypes become the real application, and you are forever stuck with the bad foundational decisions you made when slapping together that prototype that you said you wouldn’t ever deploy but that you end up deploying anyway. The ability to quickly slap something together is not a virtue.
    “JavaScript is good for beginners”

    When I hear this one, I think, “I want budding developers to learn to code with bad habits and by not learning how a real programming language works.”

    “The TypeScript compiler only finds minor errors”

    Uhm, yes. Exactly right.
    “All these types create too many errors”

    Uhm, yes. Exactly right.

    Okay, those last two comments were a bit flippant. But the errors are the point. The TypeScript compiler will find errors that could make it to deployment if not caught via testing. It is always better to find a problem earlier in the development cycle, and nothing is earlier than a little red squiggly showing up immediately as you type an error.

    As for “Too many errors,” well, that’s a feature. TypeScript is precise, and precision is good and desirable when coding. There’s no limit to the ways you can shoot yourself in the foot with JavaScript.

    “I can use unit testing to make sure my code works properly”

    This is one argument that gives me pause. I love unit testing and test-driven development, and I think we all ought to be writing our code that way, so this argument is compelling. But then I remember that you can do unit testing with TypeScript as well, so this argument kind of falls apart.

    Bad programming language, bad code

    When you say “I can develop quickly with JavaScript,” I hear “This project is going to be a maintenance nightmare.” When you say “I don’t like all that verbosity. JavaScript is simpler and more concise,” all I hear is “I like code to be inscrutable when I come back to it.” When you say “I just want to solve the problem and not deal with all those types,” I hear “I just want to create a huge pile of problems for myself later.” When you say “It’s hard to put types on everything,” I hear “Wah, wah, wah, wah.”

    Ultimately, JavaScript was the right thing at the right time. It ended up being folded, spindled, and mutilated to serve purposes that it isn’t well suited for. That’s why TypeScript came along.
