The compiler for writing next generation JavaScript.
Babel is a community-driven tool that helps you write code in the latest version of JavaScript.
When your supported environments don't support certain features natively, Babel will help you compile those features down to a supported version.
In
// ES2015 arrow function
[1, 2, 3].map((n) => n + 1);
Out
[1, 2, 3].map(function(n) {
return n + 1;
});
Try it out at our REPL and follow us at @babeljs.
