(copying this to the JS internals list) I don't know why either. Two new global objects should be equal. Does it fail with an error message? > What kind of comparism is this? Structural equivalence. To pass, the two arguments must either be === to each other, or be two different objects with the same class, the same properties in the same order, structurally-equivalent property values/getters/setters, and structurally-equivalent prototypes. As a special case, functions are not considered structurally-equivalent unless they additionally have the same source code. And off I go to check in a comment that says all that. *sheepish look* This function is implemented here: http://dxr.mozilla.org/mozilla-central/source/js/src/tests/ecma_6/shell.js#91 -j _______________________________________________ dev-tech-js-engine-internals mailing list [email protected] https://lists.mozilla.org/listinfo/dev-tech-js-engine-internals
