• Explore scope in JavaScript
• Exercise bug-finding skills related to scope issues

In this lab, you'll need to debug some issues related to function scope in #"auto">As usual, start by running the specs and reading the results. Then fix some things, run the tests again, and repeat.

You're probably pretty good at this right now — good luck!

Remember the purpose of using() is to call functions in JavaScript. It essentially tells our code toexecute the function. A function called without a(), like simplyfunctionName, will return the function but NOT run it. You'll see the return value as[Function: functionName].

To get our code to execute that function, we instead callfunctionName(), which executes the code within that function.

As an example, the third test here at first returns:Error: Expected [Function: funkyFunction] to equal 'FUNKY!'

We can make the function execute by saying this:var theFunk = funkyFunction() But this returns ANOTHER FUNCTION! How would we tell that function to execute to return the string within it?
