I have a global variable in JavaScript (actually a
windowproperty, but I don't think it matters) which was already populated by a previous script but I don't want another script that will run later to see its value or that it was even defined.I've put
some_var = undefinedand it works for the purpose of testingtypeof some_var == "undefined"but I really do not think it's the right way to go about it.What do you think?
