Well, > is used more often than >=. How would you spell "strict >"? I think when people use >, >=, etc. they almost always suppose (correctly or incorrectly) that the operands are sure to be both numbers (or both strings). If they aren't, the programmer's assumptions have already been violated; the code will likely misbehave whatever answer the language gives. That is, even if the language provided strict comparisons, and people used them, it probably wouldn't help. This stands in contrast to code like `if (x == undefined)` where there may be no presupposition at all about what sort of value x is. -j _______________________________________________ es-discuss mailing list es-discuss@mozilla.org https://mail.mozilla.org/listinfo/es-discuss
