Global vs. Local Scope in Functions

Global vs. Local Scope in Functions

---

Hints

Hint 1

Remember that global scope means that the variable is available throughout the entire code. Local scope, means that the variable is available within a certain range.

In this exercise, you have an outerWear variable in global scope with "T-shirt" as its value. You should now create another variable named outerWear, but this time within the function myOutfit(). The basic code solution is as follows:

Solution 1 (Click to Show/Hide)

var outerWear = "T-Shirt";

function myOutfit() {
  var outerWear = "sweater";
  return outerWear;
}

myOutfit();

Code Explanation

• The function will return the closest outerWear it can find. Since we created an outerWear inside the function, that is the 'closest', so the function will return "sweater".
