JS Foundation For Interview | JS series | Interview Questions

Описание: JavaScript is EVERYWHERE but how much do you actually know about it?

In this video, we break down the fundamentals of JavaScript and reveal what's actually happening under the hood. From React to NextJS - everything compiles down to HTML, CSS & JS. But your browser can technically run C++/Rust too (compiled to WebAssembly).

🎯 WHAT YOU'LL LEARN:
✅ Why React & NextJS are just frameworks (they compile to JS)
✅ JavaScript's 4 core properties (Interpreted, Dynamically Typed, Single-threaded, Garbage Collected)
✅ Why your browser CAN'T run C++ directly (but can run WebAssembly)
✅ Interpreted vs Compiled languages explained
✅ Dynamic typing in JavaScript
✅ Is JavaScript actually good? (The honest answer)
