How can I remove the last comma from this function.
for(var i = 0; i <= 100; i++) {
if(i % 2 === 0) {
div.innerHTML += l + ",";
}
else {
div.innerHTML += " ";
}
}

First, use arrays instead strings for sum strings, its faster. Second:
var arr = [];
for (var i = 0 ;i <= 100; i+=2) arr.push(l);
dividedThree.innerHTML = arr.join(', ');

in the original code, it's the lower case letter L, and it is only added every second iteration

i <= 100 ... the original result has 51 * l, not 50 :pfunction loop {
for (var i = 0; i <= 100; i++) {
if (i % 2 === 0) {
dividedThree.innerHTML += l;
if (i < 100)
{
dividedThree.innerHTML += ",";
}
} else {
dividedThree.innerHTML += " ";
}
}
}

Try using and (&&) condition for 100 and show only i value for 100.
function loop() {
var dividedThree = document.getElementById('MY_ID');
for (var i = 0; i <= 100; i++) {
if (i % 2 === 0 && i !== 100) {
dividedThree.innerHTML += i + ", ";
} else if (i === 100) {
dividedThree.innerHTML += i;
} else {
dividedThree.innerHTML += " ";
}
}
}
loop();<p id="MY_ID">
<p>

does this version work for you?
function loop() {
var data = '';
for (var i = 0; i <= 49; i++) {
data += l + ',' + ' ';
}
data += l;
dividedThree.innerHTML = data;
}
What are you trying to do? where does 'l' come from?

dividedThree.innerHTML = dividedThree.innerHTML.substring(0, dividedThree.innerHTML.length - 1);if (i % 2 === 0 && i !== 100) { ...?l? or is iti? withiyou get0, 2, 4, 6, ..., 98, 100,. the function is missing some().
