//After a week of dirtying my code editor with this challenge, i later got it right . checkout below function shortenStr (str, num){ if(str.length > num){ //checks if the length of the given string is greater than the specified number. return str.slice( 0, num ) + "..." //if the condition above is true, the slice method will start from index [0] of str and stop in the specified number adding "..." as suffix. } else {return str} // if the condition above is false, then it returns the initial string in the argument. } shortenStr("I will always code to improve my skills", 9)
