## Global vs. Local Scope in Functions

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 it's value. You should now create another variable named `outerWear`, but this time within the function `myOutfit()`. The basic code solution as follows:
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var outerWear = "T-shirt";
|
||
|
|
|
||
|
|
function myOutfit() {
|
||
|
|
var outerWear = "sweater";
|
||
|
|
return outerWear;
|
||
|
|
}
|
||
|
|
|
||
|
|
myOutfit();
|
||
|
|
```
|
||
|
|
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".
