i have simple function js so: function simple(){ } i got undefined not function error when did this: simple.prototype.apply(null,arguments); but when did this: simple.apply(null,arguments); i did not error, why on earth that? the .prototype object not have .apply() method why first example not work. .apply() method on function objects only. see mdn reference .apply() . instead, this: functionname.apply(xxx,yyy) there cases might see function on prototype object being used .apply() such as: array.prototype.slice.apply(xxx,yyy) but, again, that's calling .apply() on function since array.prototype.slice function. in specific example, simple function. so, if want call specific this value and/or pass array of arguments, proper syntax is: simple.apply(xxxx, yyy) that why syntax works - because it's proper syntax .apply() . perhaps if share problem you're trying solve , show relevant code can more specifically.
