Tell us what’s happening:
I can’t fullfill the first two parameters of the challenge:
truncateString(“A-tisket a-tasket A green and yellow basket”, 8) should return “A-tisket…”. but I get ‘a-tis…’
truncateString(“Peter Piper picked a peck of pickled peppers”, 11) should return “Peter Piper…”. => “Peter Pi…” (because I did num -3 if num…)
What should I do?
I tried to do:
str.slice(0, str.length-(str.length-num)) + ‘…’;
instead of:
str.slice(0, (num - 3)) + ‘…’;
but I caught err …
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);
