Truncate a String 2019

JavaScript

Tell us what’s happening:

I don’t even understand this one bit. Can someone walk through this problem step by step. I don’t know where the number 3 is coming from, I don’t see it anywhere in the problem’s question. The entire problem start to finish makes no logical sense to me. I tried to look at the solution for an hour. Please walk me through this.

Your code so far


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

}


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

The code I put in is not my code, its just what I wrote from the solution. In reality, I am completely stuck from the start.

Maybe you don’t understand this code because it has syntax errors.

I would search medium articles or youtube videos for detailed explanations. Here is one.
