Babel
Babel is a helpful tool that makes modern web development easier. Think of it as a translator for JavaScript code - it converts newer, advanced JavaScript code into an older version that can run on all web browsers. This is important because while developers want to use the latest coding features, they need their websites to work for everyone, even people using older browsers. It's similar to having a universal translator that ensures your website speaks a language all browsers can understand.
