How to display results after running the code

JavaScript
1

I need to display the results after running my code. Purpose is to catch the error. Console.log command won’t display no matter where I place it.
I therefore know that code does not pass certain element of the test, but don’t know why.
How to display results after running my code?
Many thanks.

Your code so far


// The global variable
var globalTitle = "Winter Is Coming";

// Only change code below this line

function urlSlug(title) {

return title
.toLowerCase()
.split(/\s+/g)
.join('-')

//Where to place console.log command to see the results?
}


// Only change code above this line

What you can do is create an intermediate variable to hold the result you want to return and then sent that to console.log before returning it.

function urlSlug(title) {
  let result = title
    .toLowerCase()
    .split(/\s+/g)
    .join('-');
  console.log(result);
  return result;
}

By the way, I believe the g flag is not necessary here. Split is always iterative.

Another strategy along with the one previously mentioned is to store the return value:

function name(){
blah...
}
let result = name()
console.log(result)

As a hint for the exercise, pass

"    hey this string"

and check what happens with the result.

Yes, it works! Thanx.

Yeap…spaces at the beginning of the string. After split, first element is a space, hyphenated with the rest of the crew, I get “-winter-is-coming”. :sweat_smile:
