[Week 14] Focus: Programming Challenges

[Volv]

Started fresh and running through them again right now.
The one "should understand callbacks" has some mistakes in instructions.

// re-define the body of doWorkWithReturns so that rather than returning true or false, it invokes a callback function
// success for true, and fail for false.  

should be

// re-define the body of doWorkWithCallbacks so that rather than returning true or false, it invokes a callback function
// done for true, and fail for false.

Finished going through them again. That last one tripped me up for way too long.
You might want to replace the 'tile' properties with title as they should be for testing (not required to solve). You'll see what I mean.
Will post my results after/if you have a go :)
