The TC39 proposal repository for JavaScript decorators, a Stage 2.7 language extension for annotating and metaprogramming ES6 classes, class methods, fields, and accessors. It contains the specification text and design history for standardizing decorators in ECMAScript.
Use cases
- understand how JavaScript decorators work
- track the standardization status of the decorators proposal
- learn to write custom class decorators
- check which class elements can be decorated in JS
- compare decorator proposal versions over time
- implement decorators in a transpiler or runtime
When to choose
- you need authoritative, up-to-date specification details on the decorators proposal
- you are implementing or evaluating decorator support in a toolchain
- you want to follow the TC39 standardization process for decorators
When to avoid
- you need a ready-to-use decorator library or runtime implementation
- you want legacy TypeScript 5 experimental decorators or Python-style decorators
- you need stable, finalized ECMAScript features rather than in-progress proposals
