Implementing Insert Function

Question

I am currently working through Khan Academy\'s algorithm course, which uses JS to teach fundamental algorithms. I am currently in the process of implementing an insertion so

Answer 1

Most of the answers posted here are correct. But It does not get us to next step in Khan Academy. It could be because Khan Academy expects a certain variable name, indent settings etc. I am not exactly sure why It does not get us to next step.

This code helped me go to next step:

var insert = function(array, rightIndex, value) {
    for(var j = rightIndex;
        j >= 0 && array[j] > value;
        j--) {
        array[j + 1] = array[j];
    }   
    array[j + 1] = value; 
};

Before I discovered this code, I used i as variable name instead of j, but it did not get me to next step. But this does.
