Ecma Test262

Tests, developer tools, and public test-running infrastructure for the JavaScript programming language.

View project

We work to maintain and improve Ecma Test262, the cannonical spec comformance test for JavaScript the programming language. We contribute tests for new features, manage EcmaScript spec changes, support contributors with reviews, maintain the overall suite as new tests are submitted,, and work on tools surrounding the tests for JavaScript engine teams.

Impact

Test262 enables JavaScript implementers to ensure that their engines comply with language standards, and helps organizations and teams that use JavaScript observe the compatibility of JavaScript runtimes in an automated way.
