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
