When a large array is passed as an argument to$.map() we get an error:

RangeError: Maximum call stack size exceeded

Tested on Chrome72 for Windows.
JQuery version:3.3.1

Sample code:

$.map(newArray(300000),i=>1)

Internally it calls toconcat.apply and crashes there.

As long as I understand,apply tries to push all elements of the array into the stack before invoking the functionconcat and fails on stack shortage.

I believe that any function being invoked thruapply with a large array as an argument will fail.

I've found about 14 usages ofapply in the code of jQuery. I would suggest you to check out all of these cases.
