# --description--
|
|
|
|
It is possible to have both <dfn>local</dfn> and <dfn>global</dfn> variables with the same name. When you do this, the `local` variable takes precedence over the `global` variable.
|
|
|
|
In this example:
|
|
|
|
```js
|
|
var someVar = "Hat";
|
|
function myFun() {
|
|
var someVar = "Head";
|
|
return someVar;
|
|
}
|
|
```
|
|
|
|
The function `myFun` will return the string `Head` because the `local` version of the variable is present.
|
|
|
|
# --instructions--
|
|
|
|
Add a local variable to `myOutfit` function to override the value of `outerWear` with the string `sweater`.
|
|
|
|
# --hints--
|
|
|
|
You should not change the value of the global `outerWear`.
|
|
|
|
```js
|
|
assert(outerWear === 'T-Shirt');
|
|
```
|
|
|
|
`myOutfit` should return the string `sweater`.
|
|
|
|
```js
|
|
assert(myOutfit() === 'sweater');
|
|
```
|
|
|
|
You should not change the return statement.
|
|
|
|
```js
|
|
assert(/return outerWear/.test(code));
|
|
```

// Setup
|
|
var outerWear = "T-Shirt";
|
|
|
|
function myOutfit() {
|
|
// Only change code below this line
|
|
|
|
|
|
|
|
// Only change code above this line
|
|
return outerWear;
|
|
}
|
|
|
|
myOutfit();
|
|
```
|
|
|
|
# --solutions--
|
|
|
|
```js
|
|
var outerWear = "T-Shirt";
|
|
function myOutfit() {
|
|
var outerWear = "sweater";
|
|
return outerWear;
|
|
}
