The TC39 proposal repository that introduced async/await syntax into the ECMAScript language, including the full specification text and examples. The feature has been merged into the JavaScript standard and is now supported natively in all modern runtimes.

Use cases

  • understand how async/await was specified for JavaScript
  • read the ECMAScript spec text for async functions
  • learn the history of the async/await proposal
  • find the regenerator-based ES5 transpilation example
  • reference async function semantics like AsyncFunctionCreate

When to choose

  • you need the authoritative specification details for async functions
  • you are researching TC39 proposal process or language design history
  • you need to transpile async/await to ES5 via regenerator

When to avoid

  • you just want to use async/await in modern JavaScript - it is built into the language
  • you need a runtime library or tool rather than a specification document
