Overview

Error Maximum call stack size exceeded is raised when calling a recursive function in a loop

This is expected as every javascript Engine has a maximum Call Stack Range Failing Javascript Code function errorFunc(rc) {
var runCount = rc;
var maxCount = 100000;
if ( (rc % 5000) === 0 ) {
logMessage("errorFunc():: Recursion Count: " + runCount );
}
runCount++;
if (runCount >= maxCount ) {
logMessage("errorFunc() reached MAX recursion Count : " + runCount );
return;
}
try {
errorFunc(runCount);
} catch (e ) {
if ( e instanceof RangeError) {logMessage("errorFunc():: " + e + ": " + runCount );
}
}
};
Output
Avoid Maximum call stack size exceeded in JavaScript
Fixed Code be using setTimeout() function Workraound : use setTimeout() function setTimeout() function always creates a Top Level Function function workingFunc(rc) {
// logMessage("workingFunc()");
var runCount = rc;
var maxCount = 100000;
if ( (rc % 20000) === 0 ) {
logMessage("workingFunc():: Recursion Count: " + runCount );
}
runCount++;
if (runCount >= maxCount ) {
logMessage("workingFunc() reached MAX recursion Count : " + runCount );
return;
}
try {
setTimeout( workingFunc, 0, runCount);
} catch (e ) {
if ( e instanceof RangeError) {logMessage("workingFunc():: " + e + ": " + runCount );
}
}
}; Output of fixed Code
Avoid Maximum call stack size exceeded in JavaScript
Note: The setTimeout() Workaorund is very slow References Recursion Details JsFiddle Code [ Tested with Google Chrome Browser ]
