The official TC39 repository tracking ECMAScript (JavaScript) language proposals across all maturity stages, from stage 0 ideas to finished standard features. It serves as the canonical index of the committee's work on evolving the JavaScript specification.
Use cases
- track upcoming JavaScript language features
- find out which ECMAScript proposals are at stage 3
- check the status of a specific JS proposal
- learn how the TC39 proposal process works
- see which proposals have been finished or withdrawn
- research future JavaScript syntax before adopting transpiler features
When to choose
- you need the authoritative, up-to-date list of ECMAScript proposals and their stages
- you want to follow or contribute to JavaScript language design
- you're evaluating whether to polyfill or transpile an upcoming JS feature
When to avoid
- you need a software library or tool rather than documentation
- you want finalized JavaScript documentation instead of in-progress proposals
