Truncating strings help!

Tell us what’s happening:
Doesn’t return the correct value

Your code so far


function truncateString(str, num) {
  // Clear out that junk in your trunk
  if (str.length <= num) {
    return str;
  } else {
    return str.slice(num + 1) + '...';
  }
}

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

I am certain you are not using slice correctly.

3

I don’t know what is wrong with my slice. I specify where to start and to cut out the rest of the string.

4

I only see one argument being passed.

5

You are misinterpreting how it works.

Did you read the link to the documentation I gave? What does the example show you?

7

I did read it a bit, I don’t think i found anything useful

8 
var animals = ['ant', 'bison', 'camel', 'duck', 'elephant'];

console.log(animals.slice(2));
// expected output: Array ["camel", "duck", "elephant"]

Is this the kind of behavior you want in your current code?

Ahh, I see, it takes out what isn’t specified. I though it did the opposite.
Thanks I understand now.
