What is the JavaScript Stack Size Limit in IE and How Can I Find It?

IE Browser Javascript Stack Size Limit

Javascript stack overflow errors in IE browsers can hinder the execution of complex functions. This issue arises due to the browser's limited stack size compared to other popular browsers. To determine the stack size limit, a simple HTML test can be performed:

<code class="html"><head><script>
function doSomething(i) {
  if (i == 0) return -1;
  doSomething(i-1);
}

doSomething(3200);
</script></head><body></body></code>

Copy after login

In IE, a stack overflow occurs around 3200 while browsers like Firefox and Chrome can handle considerably deeper recursion.

Tracking the Overflow Source

In case of a stack overflow, it is helpful to identify the specific function that caused the error. Unfortunately, most browsers do not provide a built-in mechanism to trace JavaScript stack frames. However, a workaround can be employed using a try/catch block:

<code class="javascript">var i = 0;
function inc() {
  i++;
  inc();
}

try {
  inc();
}
catch(e) {
  // Manual adjustment for StackOverflow sandbox
  i++;
  console.log('Maximum stack size is', i, 'in your current browser');
}</code>

Copy after login

This code gradually increments a counter until a stack overflow occurs. The caught error allows you to determine the browser's maximum stack size, which can provide insightful information when debugging stack overflow issues.
