Truncate a String?

JavaScript
1

Tell us what’s happening:
Not sure why I am struggling with this code.
\problem:
truncateString(“A-tisket a-tasket A green and yellow basket”, 8) should return “A-tisket…”.
truncateString(“Peter Piper picked a peck of pickled peppers”, 11) should return “Peter Piper…”.

Your code so far


function truncateString(str, num) {
  // Clear out that junk in your trunk
  if (str.length > num && num > 3) {
    return str.slice(0, (num - 3)) + '...';
  } else if (str.length > num && num <= 3) {
    return str.slice(0, num) + '...';
  } else {
    return str;
  }

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

Compare your output with test cases using console.logs.

The first test case should return below.

But your code is returning this instead.

A-tis…

Thank you so much! Got it now. Took away - 3 from (num - 3) in my first argument
