Test262 is a test suite that may be used to check how closely a JavaScript implementation follows the standard - ECMAScript 5th Edition Specification. The test suite contains thousands of individual tests, each of which tests some - specific requirements of the ECMAScript specification. -
Test262 is not yet complete, and is still undergoing active development. Please do not read too much - into the test results below at this time.
-Some portions of the ES5 specification have very complete test coverage while other portions of the specification have only - partial test coverage. Some tests may be invalid or may yield false positive or false negative results. A perfect passing score - on Test262 does not guarantee that a JavaScript implementation perfectly supports ES5.
-Below are Test262 test results that have been submitted by various browser vendors. Note that slightly different versions - of Test262 may have been used for each result set. Because tests are being actively added and modified, detail test results - from different Test262 versions may not be directly comparable.
