Challenge: Local Scope and Functions

Variables which are declared within a function, as well as the function parameters have local scope. That means, they are only visible within that function.

Here is a function myTest with a local variable called loc.

function myTest() {
  var loc = "foo";
  console.log(loc);
}
myTest(); // "foo"
console.log(loc); // "undefined"

loc is not defined outside of the function.

Something went wrong with that request. Please try again.
