ECMAScript
This repo
This repository contains the source for the current draft of ECMA-262,
the ECMAScript® Language Specification.
This source is processed to obtain a human-readable version,
which you can view here.
If you want to explore how the specification was written, you can also view the source with its history in searchfox.
Current Proposals
Proposals follow the TC39 process and are tracked in the proposals repository.
Contributing New Proposals
Please see Contributing to ECMAScript for the most up-to-date information on contributing proposals to this standard.
Developing the Specification
After cloning, do npm install to set up your environment. You can then do npm run build to build the spec or npm run watch to set up a continuous build. The results will appear in the out directory, which you can use npm run clean to delete.

Overview (`biblio/README.md`)
ECMA-262 Bibliography
This package, available on npm as @tc39/ecma262-biblio, contains a machine-readable representation of the terms, clauses, grammar, and abstract operations defined in ECMA-262. This will primarily be of use to people working with the specification itself.
If added as a dependency to a project using ecmarkup, you can load it by passing --load-biblio @tc39/ecma262-biblio.
It is automatically updated whenever ECMA-262 is. It is inherently unstable: editorial changes to the specification may add, remove, or modify the biblio, which may break your build (for example, if using ecmarkup with --lint-spec --strict). As such, the usual semver guarantees do not hold. You should pin a precise version of this package.
Major version bumps may be used for breaking changes to the format of the biblio itself. Minor version bumps may be used for non-breaking additions to the biblio format.
