new AbortController();See CONTRIBUTING.md for getting started with Babel. In short, after cloning and running make bootstrap, the workflow looks like this
# builds all packages
make build
# test changes
cd examples
./run.shPR's welcome, especially for adding some of the simple keyword replacements. See babel-parser and the first commit that diverged from upstream for details. After modifying the keyword, simply edit any injected Babel helper functions or used Babel templates with your replacement syntax and it should work (an error will show on build and you can globally search for it). You don't have to edit every instance, just the minimum required to get it to work.
The compiler for writing next generation JavaScript.
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 Patreon!
Our top sponsors are shown below! [Become a sponsor]
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
// ES2020 nullish coalescing
function greet(input) {
return input ?? "Hello world";
}Out
function greet(input) {
return input != null ? input : "Hello world";
}Try it out at our REPL.
Mostly a handful of volunteers, funded by you! Please check out our team page!
