The exception of too much recursion or maximum call stack size exceeded occurs when there are many function calls, or even if a function is missing a base case.
Output message:
Error: Out of stack space (Edge) InternalError: too much recursion (Firefox) RangeError: Maximum call stack size exceeded (Chrome)
Error Type:
InternalError
A recursive function is a function that calls itself repeatedly. When a condition is met, the function stops calling itself. This is called a base case. If somehow the condition does not meet then the function continues calling itself and the error occurs.
Example 1: This example works perfectly, without errors. Because the stopping condition is when x >= 5.
Javascript
function recursion(x) {Â
    // Base case    if (x >= 5)        return;    recursion(x + 1); // The recursive call}Â
function Geeks() {Â Â Â Â try {Â Â Â Â Â Â Â Â recursion(0);Â Â Â Â Â Â Â Â console.log("Too much "Â Â Â Â Â Â Â Â Â Â Â Â + "recursion error not occurred");Â Â Â Â } catch (e) {Â Â Â Â Â Â Â Â console.log("Too much "Â Â Â Â Â Â Â Â Â Â Â Â + "recursion error occurred");Â Â Â Â }}Â
Geeks(); |
Output
Too much recursion error not occurred
Example 2: In this example, the stopping condition is when x >= 1000000000000. This is a large value, so the error occurred.
Javascript
function recursion(x) {Â
    // Base case    if (x >= 1000000000000)        return;    recursion(x + 1); // The recursive call}function Geeks() {    try {        recursion(0);        console.log("Too much recursion"            + " error not occurred");    } catch (e) {        console.log("Too much recursion"            + " error occurred");    }} Â
Geeks(); |
Output
Too much recursion error occurred
