Challenge: Truncate a String

Link to the challenge:

The function will always be called with num, so it will never enter the else-code.

Also try calling it with a number bigger than the length of the string and you will notice the first part also isn’t working.

so what to do to solve??

if num what?
when is it that you need to truncate the string?

if the string length is greater than num.

then you need to use that as condition for the if statement

ok but the dots are not going

what’s your code now?

it is working now

    return str.slice(0,num)+"..."
    return str

good job!

Happy coding!
