Supporting Babel
Babel (pronounced "babble") is a community-driven project used by many companies and projects, and is maintained by a group of volunteers. If you'd like to help support the future of the project, please consider:
- Giving developer time on the project. (Message us on Twitter or Slack for guidance!)
- Giving funds by becoming a sponsor on Open Collective or GitHub (which goes to our Open Collective account)!

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.
