Every couple of years, the front-end community buries JavaScript. Sometimes articles come out with the words "outdated", then there is a hype around WebAssembly, then the mass transition to TypeScript makes it feel like "JS itself is not needed". Amidst all the noise, it's easy to believe that the language is about to give up its throne.
But if you look closely, it is JavaScript that remains the invisible framework of the modern web. It's in the browser, it's in the developer tools, it's on the server via Node.js and Deno. In 2025, JS again proves that the king is alive and the crown is still there. Let's figure it out — without fanaticism, but also without panic.
Why did we even start talking about the "death" of JavaScript? ⚰️
TypeScript is everywhere
It seems that "TS has replaced JS". In fact, TS is compiled into JS — the base is still there.
The ecosystem is complex
Many frameworks and tools → it is not easy for beginners, hence the feeling of "chaos".
WebAssembly is gaining weight
Interest in "foreign" languages in the browser creates the illusion of competition.
Why is JS alive and kicking?
TS is an add-on, not a replacement
Types help projects grow, but JS is always executed.
Frameworks on JS
React, Vue, Svelte, Angular — the whole scene revolves around the JavaScript runtime model.
JS outside the browser
Node.js/Deno on the server, Electron/Tauri on the desktop, React Native/Ionic on mobile.
Coupling with WebAssembly
In most cases, it is JS that "glues" WASM modules with DOM, events and the network.
Community and packages
The incredible speed of development and the number of libraries is a serious competitive advantage.
Frontend in 2025: JavaScript is the base 🧩
Even when you write in TypeScript, when you call the WebAssembly module or use the new assembler, JavaScript works under the hood. This is the "default language" for the browser and the main glue that connects the API, UI, and data.
The conclusion is simple: arguing "whether JS is needed" is like arguing "whether markup is needed on the web". It is needed. The question is not "JS or not", but how effectively you use it.
Typical mistakes and how to avoid them?
Jump between frameworks every week → choose one stack for 2-3 months.
Learn "in theory" → each block is fixed with a mini-project.
Ignore JS base because of TS → understand what your code is compiling into.
Watch only tutorials → read the documentation and library sources.
JavaScript is not dead and is unlikely to die. It changes, grows up and remains the foundation on which the frontend is built. Learn from projects, analyze modern syntax, connect TypeScript as you grow — and you will get a stack that is in demand here and now.
