In the fast-evolving world of web development, JavaScript moves at a pace that browsers can’t always keep up with. While developers want to use the latest ECMAScript (ES6+) features to write cleaner, more efficient code, they must ensure their applications still run on older browsers. This is where babel-loader becomes indispensable.

: It allows you to use experimental features (like decorators or optional chaining) before they are officially supported by all browsers. Core Components of the Setup babel-loader

To get babel-loader working, you typically need three primary dependencies: babel-loader - webpack In the fast-evolving world of web development, JavaScript
