All web browsers, and most other JavaScript environments, have shipped some form of developer console. This standard attempts to finally define the semantics of the console APIs, in an attempt to create convergence.

A list containing some of the observed differences so far in different environments is available in NOTES.md.

This specification is still in its very early stages. It is very much a work in progress.

Tests can be found in the console/ directory of web-platform-tests/wpt.

For guidelines on how to build and edit the spec, see CONTRIBUTING.md.

If you can commit to this repository, see the WHATWG Maintainer Guidelines.

We are committed to providing a friendly, safe, and welcoming environment for all. Please read and respect the WHATWG Code of Conduct.
