Appear only on the fourth iteration

Question

How can I make 'congrets' appear only on the fourth iteration

if(Object.keys(num1)[i].length === 4)
{
correction.innerHTML = congrets;
} else if (Object.keys(num1).length[i] < 1) {
correction.innerHTML = "1st string";
} else {
correction.innerHTML = "2nd string";
}

Answer 1

I see a potential error: you only have 1 equals operator in the if statement

Answer 2

try

if(Object.keys(num1)[i].length === 4){
//your code goes here
}

Answer 3

Oh my God. You guys are amazing.
The code:

if (i==3)
{
numcount.innerHTML = congrets;
}

works perfectly fine. It was really a lets go ahead and do this thing. This was really an innovation.

//if iteration begins from zero
