Any idea why JSON left out NaN and +/- Infinity? It puts Javascript in the strange situation where objects that would otherwise be serializable, are not, if they contain NaN or +/- infinity values.

Which (javascript) environments support ECMAscript 5 strict mode? (aka "use strict")

ECMAScript 5 is in its final draft as I write this; It is due to include a strict mode which will prevent you from assigning to the global object, using eval, and other restrictions. (John Resig's Article is a good introduction.) This magical sanity-saving mode is triggered by including the string "use strict" at the top of your file (o...
