Truncate a String0

Tell us what’s happening:

Help me out with this and Thanks in advance.

Your code so far


function truncateString(str, num) {
  // Clear out that junk in your trunk
  if (str.length <= num) {
      return str;
  }
  else
  {
     
  }
}

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

I did not understand, explain me what to do if str.length > num. i will write the code

You need to make the string shorter (the length is num) and add three dots at the end to show that you have shortened the string

5

still these first two test cases are not working. if there is something wrong or need an explanation please let me know.

What happens if str.length is less than or = 3?

9

it returns str in the else part

10

Doesn’t it need “…” somewhere?

11

console.log(truncateString(“A-tisket a-tasket A green and yellow basket”, 8));
returns: A-tis… (with your code).
which is 8 characters, but you want 8 characters + “…”
Look at your first if statement (does num have to be > 3?). Then edit the return for the first if statement accordingly.

Edit: My answer was for code in another question that was referring to the “hint answer” that got merged with this question because it was a duplicate. So what I said above refers to the hint answer.

Your issue is still the same, you can’t use the solution from the guide, because t counts the dots inside the limit of characters. Instead the length of the str is max num and after truncated you add the dots
