DESCRIPTION:

Truncate a string (first argument) if it is longer than the given maximum string length (second argument). Return the truncated string with a ... ending.

Examples

truncateString("Peter Piper picked a peck of pickled peppers", 11)
 //should return the string `Peter Piper....`

truncateString("A-tisket a-tasket A green and yellow basket",
 "A-tisket a-tasket A green and yellow basket".length)
//should return `A-tisket a-tasket A green and yellow basket.`

My approach for solving this problem:

• check the str length.
• if the length is equal to num return str
• if not return sliced str with num length

My solution:

function truncateString(str, num) {
  let slicedstr;

  if(str.length > num){
    slicedstr = str.slice(0,num)+"..."
  }else{
    slicedstr = str
  }

  return slicedstr;
}

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