How to Fix 'Maximum Call Stack Size Exceeded' and 'JS: Execution Exceeded Timeout' Errors in Safari?

Resolving "Maximum Call Stack Size Exceeded" and "JS: Execution Exceeded Timeout" Errors

When encountering the "Maximum call stack size exceeded" error in Safari, it signifies that your code has an excessive number of nested function calls. This issue can prevent further processing and result in a complete halt of the execution. In the iPad Safari browser, this error may manifest as "JS: execution exceeded timeout."

Understanding the Error

The call stack is a memory space that stores information about function calls. Each time a function is called, a new stack frame is created. If the stack reaches its maximum size, as it can in the case of excessive nesting, the error is triggered.

Fix for Safari Browser

To resolve this issue, ensure that your recursive functions have a clear base case. A base case is a condition that, when met, stops the recursive call and effectively unwinds the stack.

For example, consider the following recursive function:

function a() {
    a();
}

This code will trigger the error because there is no base case to stop the recursion. To fix it, we can add a base case that checks if the function has been called a certain number of times or if a particular condition has been met:

function a(x) {
    if (x > 10) {
        return;
    }
    a(--x);
}

In this updated code, the base case is when x is greater than 10, ensuring that the recursive call will not exceed the maximum stack size.
