What is the problem allowing following instead of above? a = myObject.anArray; a[-1]; a[-2] = "foo"; And I see, I can reduce a lot of my code if I can do a[ - a_var_with_postive_value] = "foo"; > It would be incompatible, since a[-1] means the same thing for arrays > as for objects: the property named "-1". And I dont think any body depending on such code now, ie expecting "-1" as property name in Array _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
