56533eb9ac21ba0edf2244c0	Global vs. Local Scope in Functions	1	https://scrimba.com/c/c2QwKH2	18194

--description--

It is possible to have both local and global variables with the same name. When you do this, the local variable takes precedence over the global variable.

In this example:

var someVar = "Hat";
function myFun() {
  var someVar = "Head";
  return someVar;
}

The function myFun will return "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 "sweater".

--hints--

You should not change the value of the global outerWear.

assert(outerWear === 'T-Shirt');

myOutfit should return "sweater".

assert(myOutfit() === 'sweater');

You should not change the return statement.

assert(/return outerWear/.test(code));

--seed--

--seed-contents--

// Setup
var outerWear = "T-Shirt";

function myOutfit() {
  // Only change code below this line



  // Only change code above this line
  return outerWear;
}

myOutfit();

--solutions--

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