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) { // Base case if (x >= 5) 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"); }}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) { // 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"); }} Geeks(); |
Output
Too much recursion error occurred
