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);
