                 <p class="content"><strong>test262 is not yet complete.  It is still undergoing active development.</strong> 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. Because tests are being actively added and modified, tests results from different days or times may not be directly comparable.
