🔥 What Every Web Developer Should Know About JavaScript

JavaScript was created in 10 days by Brendan Eich — speed ≠ simplicity. Master the fundamentals.

It’s not Java — different languages, different ecosystems.

ECMAScript is the spec; JavaScript is the implementation you write daily.

ES6 (2015) changed everything: let/const, arrow functions, classes — know them deeply.

Node.js made JavaScript full-stack — frontend + backend with one language.

Async is core: understand promises, async/await, and the event loop.

The browser is your runtime — learn the DOM, not just frameworks.

Frameworks change. JavaScript fundamentals don’t.

TypeScript is powerful — but it sits on top of JavaScript, not instead of it.

AI can generate code — but only knowledge helps you debug, optimize, and scale it.

💡 Bottom line: If you skip the basics, you’re not coding—you’re guessing.
