Master React JS: The Role of Babel, ES6 vs ES5, & JavaScript History | Ep 02
What is Babel in React JS? | Understanding JS History, ES5 vs ES6, & Compilers 🚀
About This Video:
Welcome back to NeuralScript Labs! In Episode 02 of our React JS Full Course 2026, we dive deep into the "engine" that makes modern React code run on every browser: Babel.
Before writing complex React code, it’s crucial to understand how it works under the hood. In this video, we explore the history of JavaScript, the evolution from ES5 to ES6, and why we need a compiler like Babel to translate our modern JSX code for older browsers.
What You Will Learn:
📜 JavaScript History: From Mocha and LiveScript (1995) to modern JS.
⚔️ ES5 vs ES6: Why the 2015 update (ES2015) changed everything for developers.
🤖 What is Babel? A deep dive into the most popular JavaScript Compiler.
🛠️ Babel's Role in React: How it converts JSX and ES6+ into browser-compatible ES5.
🚀 Automatic Setup: How create-react-app handles Babel for you out of the box.
