Maximum call stack size exceeded error

The error message "Uncaught RangeError: Maximum call stack size exceeded " occurs when a JavaScript function recurses excessively, causing the call stack to overflow and exceed its maximum size limit. This error usually indicates an infinite or uncontrolled recursion, where a function calls itself repeatedly without proper termination conditions.

Reasons for this error

Infinite Recursion

When a function keeps calling itself without a base case or termination condition, it leads to an infinite loop of function calls.

Deep Recursion

Even with proper termination conditions, if a recursion goes too deep without returning, it can still result in a stack overflow.

function infiniteRecursion() { infiniteRecursion(); // Calls itself indefinitely } infiniteRecursion(); // This will lead to "Uncaught RangeError: Maximum call stack size exceeded"

How to solve this error

Base Case

Ensure that your recursive function has a proper base case or termination condition that stops the recursion. This condition should be met at some point to prevent infinite recursion.

function factorial(n) { if (n === 0) { return 1; // Base case } return n * factorial(n - 1); }
  1. Correct Logic: Verify that your recursive function's logic is correct and follows the intended flow.
  2. Check Looping: Ensure that you're not inadvertently causing a loop that continuously invokes the function.
  3. Limit Depth: If your recursion is intentionally deep, consider optimizing your code to minimize the depth of recursion.
  4. Iterative Approach: If possible, consider using an iterative approach instead of recursion to achieve the same result.
  5. Debugging Tools: Use debugging tools like browser developer consoles or Node.js debugger to trace the recursion and identify where the error occurs.
  6. Tail Recursion: Tail recursion optimization can sometimes mitigate stack overflow issues. However, JavaScript engines don't currently provide full support for tail call optimization.
  7. Memoization: In some cases, memoization (caching intermediate results) can reduce the number of recursive calls and improve efficiency.

Memory limit of Call Stack

Javascript RangeError: Maximum call stack size exceeded

The Call Stack is a crucial programming concept used to manage method calls in a program. Comprising stack frames, each representing a method call, it is primarily employed for function invocation. Function execution occurs sequentially, one at a time, in a top-to-bottom manner due to the single nature of the call stack, making it synchronous.

Upon entering a function, its corresponding entry is pushed onto the Call Stack, and upon exiting, the same entry is popped. Each method call introduces a new stack frame, consuming space on the call stack. This has implications for the space complexity of algorithms, especially in recursive scenarios. Excessive arguments or uncontrolled recursive calls can lead to the "Maximum call stack size exceeded" error, indicating that the call stack's limit has been surpassed. For example:

alert.apply(window, new Array(1000000000));

The capacity of the call stack is finite, and it's important to be mindful of its limitations when dealing with functions and their arguments. In scenarios such as using Array.apply(null, new Array(1000000)), the operation has the potential to overwhelm the call stack's memory.

In this specific case, the Array.apply(null, new Array(1000000)) constructs a large array, and when applied as arguments to a function, each array element becomes a separate argument. As a result, a substantial number of local variables are introduced, effectively increasing the memory usage of the current stack frame. This can lead to the "Maximum call stack size exceeded" error due to the excessive memory consumption, crossing the boundary of what the call stack can accommodate.

In some programming languages this can be solved with tail call optimization, where the recursion call is transformed under the hood into a loop so no maximum stack size reached error exists.


The "Uncaught RangeError: Maximum call stack size exceeded" error occurs when a JavaScript function enters into excessive recursion, overwhelming the call stack's capacity. This error indicates that the function is calling itself indefinitely or going too deep without proper termination conditions, leading to a stack overflow.
