I love the way barbel has the ability to turn ES6 code into regular vanilla JS, old versions of JavaScript to new versions and recently helped me transform normal JavaScript to react code, this a handy function that makes working with new JavaScript frameworks through syntax transform. this transformer is well documented, it very easy to target new JavaScript capabilities in browsers, this allows to ignore or point to specific targets for example working with a bandler like webpak as part of a compilation pipeline. there are other additional dependencies that can be added

Not only are you able to use the latest features, you can also implement experimental javascript features that haven't yet been implemented in the language and babel will compile it down into a javascript version every browser can understand. Babel website provides an editor where you can paste your code or type any javascript code and it will preview the transpiled code.

Babel transpiles javascript code that is using the latest features or features that are yet to be standardised into code that all browsers can understand. It is a very important to for writing cross browser Javascript instead of having to write code specific to target browsers.
