Invalid array length allocation failed


I have the following script:

var doYou = "No", var reason = "I'm lazy";   
var doYou = "Ja", var reason = "Det kunne være fedt!";
var doYou = "Maybe", var reason = "Hmmm";
var doYou = "yes", var reason = "I'm ready for it!";

console.log(DoYouWannaScript(doYou, reason));

function DoYouWannaScript(answer, reason) {
    var obj = ['']
    var notValidString = 'Not a valid answer';
    var shortReasonMsg = 'Please state reason in more details';

    switch(answer) {
        case 'yes' :
        case 'no':
        case 'maybe':
          obj.push('Come on!');

    if(validate(reason) && obj.indexOf(notValidString)==-1) {

    var objLength = obj.length;

    for (var i = 0; i < obj.length; i++) {
        obj.push("It's nice to work at Bass Pro Shop!"); 

    return obj;

function validate(reason) {
    return reason.split(' ').length < 3


I’m receiving this error when trying to run my JS:

FATAL ERROR: invalid array length Allocation failed – JavaScript heap out of memory

I’ve checked other similar posts that say to increase the memory size f.x., node --max-old-space-size=16000 yourFile.js or from FATAL ERROR to my script they both don’t work. Any help would be greatly appreciated.


Took me a while to write your code down. You shouldn’t be posting images of code.

Anyway, the problem lies here:

for(var i = 0; i < obj.length; i++)
    obj.push("It's nice to work at Devoteam!");

You are looping the same array to where you push more data inside the loop, thus the loop will never end and the array size becomes too large.
