![]() ![]() The screenshot below shows what recursive code looks like when it calls on itself indefinitely. Then, to solve the problem, specify a base case that must be satisfied to exit the recursion. The issue with a recursive function that continues to call on itself is that it is impossible to move on to the following function within a chain, and you’ll eat up the entirety of your stack.ĭouble-checking your recursive functions is the best approach to avoid this issue. When recursive code doesn’t have its base code or shoots past it, it will keep calling itself until the browser’s Maximum Call Stack is reached. The most common cause of a recursive function’s Maximum call stack size exceeded error is a problem with the base case or the lack thereof. However, if you’re not careful, a function can continuously call itself until the browser’s stack is depleted. You can just remove the subscribe, the async pipe. Recursion is a pattern in which a defined function calls itself, with each iteration moving conditions closer to a base case that allows an escape from the function calls. The reason you are receiving maximum call stack size exceeded is because you have an infinite loop, you are subscribing to filteredEvents, then in the subscription you are emitting value to filteredEvents, which triggers the subscription again, effectively causing an infinite loop. Still, you need to understand recursion before understanding the Maximum call stack size exceeded error. Now that you know a bit of where this error falls within the scope of JavaScript errors let’s continue to what causes the Maximum call stack size exceeded error. This is referred to as a RangeError.Ī RangeError often indicates an error outside a code’s parameter’s argument value. With the help of this JavaScript article, you will go over in great detail why a Maximum call stack size exceeded error shows up and what you can do to fix it.Īll JavaScript error objects are descended from or inherited from the Error object. When this error occurs, there are several steps you can take to fix the piece of code that is eating up all the available call stacks within a browser. Maximum call stack size exceeded Error in JavaScript More particularly, the problem is with the function, which keeps calling on itself repeatedly. Sometimes calling a recursive function over and over again, causes the browser to send you Maximum call stack size exceeded error message as the memory that can. In the interest of that, here is my call stack as shown in the Firebase Emulator logs. missing base case in a recursive function to stop calling itself infinitely. This can occur due to the following reasons: Too many function calls. If the JavaScript’s Maximum call stack size exceeded error occurs, the problem lies with the recursive function within your JavaScript code. The RangeError: Maximum call stack size exceeded is thrown when a function call is made that exceeds the call stack size. The JavaScript’s Maximum call stack size exceeded error occurs when a function is called so many times that the invocations exceed the maximum call stack limit. Maximum call stack size exceeded Error in JavaScript.This structure is in a last-in-first-out format. ![]() The call stack is a data structure in JavaScript that contains the function(s) being executed. But what does this mean?įirst, let's understand what the call stack is. Have you ever gotten an error similar to this? This error occurs because the call stack has exceeded its limit. ![]()
