Maximum call stack size exceeded error

Solution 1:

It means that somewhere in your code, you are calling a function which in turn calls another function and so forth, until you hit the call stack limit.

This is almost always because of a recursive function with a base case that isn't being met.

Viewing the stack

Consider this code...

(function a() {
    a();
})();

Here is the stack after a handful of calls...

As you can see, the call stack grows until it hits a limit: the browser hardcoded stack size or memory exhaustion.

In order to fix it, ensure that your recursive function has a base case which is able to be met...

(function a(x) {
    // The following condition 
    // is the base case.
    if ( ! x) {
        return;
    }
    a(--x);
})(10);

Solution 2:

You can sometimes get this if you accidentally import/embed the same JavaScript file twice, worth checking in your resources tab of the inspector.

Solution 3:

In my case, I was sending input elements instead of their values:

$.post( '',{ registerName: $('#registerName') } )

Instead of:

$.post( '',{ registerName: $('#registerName').val() } )

This froze my Chrome tab to a point it didn't even show me the 'Wait/Kill' dialog for when the page became unresponsive...

Solution 4:

There is a recursive loop somewhere in your code (i.e. a function that eventually calls itself again and again until the stack is full).

Other browsers either have bigger stacks (so you get a timeout instead) or they swallow the error for some reason (maybe a badly placed try-catch).

Use the debugger to check the call stack when the error happens.
