What is Babel JavaScript?

Answer 1

Hi there. Basically babel is a tool that converts ECMAScript 2015 and above into javascript that is backward compatible with browsers that don't support ECMAScript 2015 and above. Check out an example from the babel page:

// Babel Input: ES2015 arrow function

[1, 2, 3].map((n) => n + 1);

// Babel Output: ES5 equivalent

[1, 2, 3].map(function(n) {

return n + 1;

});

Reading the documentation is always the best way to go but I hope this helps you understand the basic idea of babel.
