Truncate a String problem output

JavaScript

Help, im a bit stuck in this problem, i don’t know why the for loop surpasses the max number

  **Your code so far**


function truncateString(str, num) {
let text = str.split("");
let result = [];


if (str.length >= num){
for (let i = 0; i < num; i++){
  result.push(text[i])
}
result = result.join("") + "...";
console.log(result);
}else{
result = str;
}

//console.log(result);
return result;
}

truncateString("A-tisket a-tasket A green and yellow basket", 8);

console.log("A-tisket a-tasket A green and yellow basket".length + 2);
console.log("A-tisket a-tasket A green and yellow basket".length);

If the number is equal to the length of the string, do you want to be putting ‘…’ at the end? You should only be running the code inside this block if num is greater than the length of the string.

No problem!

And sorry, I said this wrong. I meant ‘if the length of the string is greater than num’. :joy:

yeah I got the logic already right yesterday, on that code you mentioned and it passed the test. :ok_hand:
