Code works but challenge not passed

Hi. I am at debugging part of JS and I have to fix two errors in a code to print all the numbers from 1 to 5. I wrote a code a bit different, just wrote

for (let i = 0; i <= len-1; i++)

instead of

for (let i = 0; i < len; i++)

which i think is the same? But they say that

Your code should set the terminal condition of the loop so it stops at the last index.

It does tho? It prints numbers 1 2 3 4 5.
Am i missing something?
Your code so far


function countToFive() {
let firstFive = "12345";
let len = firstFive.length;
// Only change code below this line
for (let i = 0; i <= len-1; i++) {
// Only change code above this line
  console.log(firstFive[i]);
}
}

countToFive();

Challenge: Catch Off By One Errors When Using Indexing

Link to the challenge:

function countToFive() {
  let firstFive = "12345";
  let len = firstFive.length;
  // Only change code below this line
  for (let i = 0; i <= len-1; i++) {
  // Only change code above this line
    console.log(firstFive[i]);
  }
}

This is technically correct, but it is more ideomatic to see i < len, so this is what the tests want.
