Intro
Babel is a 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
1// ES2020 nullish coalescing 2function greet(input) { 3 return input ?? "Hello world"; 4}
Out
1function greet(input) { 2 return input != null ? input : "Hello world"; 3}
Try it out at our REPL.
