Description
When a large array is passed as an argument to $.map()
we get an error:
RangeError: Maximum call stack size exceeded
Tested on Chrome 72 for Windows.
JQuery version: 3.3.1
Sample code:
$.map(new Array(300000), i => 1)
Internally it calls to concat.apply
and crashes there.
As long as I understand, apply
tries to push all elements of the array into the stack before invoking the function concat
and fails on stack shortage.
I believe that any function being invoked thru apply
with a large array as an argument will fail.
I've found about 14 usages of apply
in the code of jQuery. I would suggest you to check out all of these cases.
