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

From the challenge:

Although there are many ways to write this function, you should write it in a way that is consistent with the hint code.

It's strictly checking for this:

var ___;
for(___ = ___; ___; ___) {
    array[___ + 1] = ___;
} 

So even though these two alternates are correct:

while(array[rightIndex] > value && rightIndex >= 0) {
    array[rightIndex + 1] = array[rightIndex];
    rightIndex--;
}
array[rightIndex + 1] = value;

And especially this almost identical one (switched the middle statement in the for loop):

for(var i = rightIndex; array[i] > value && i >= 0; i--) {
    array[i + 1] = array[i];
}

array[i + 1] = value;

This one is the answer:

for(var i = rightIndex; i >= 0 && array[i] > value; i--) {
    array[i + 1] = array[i];
}

array[i + 1] = value;

Ironically, it doesn't care about the useless first variable in the hint...

var ___;
