Frequently asked questions

Q.1) Can you remind me what functions are?

A) Functions are containers for our code that can be executed (called) from other parts of our code.

Q.2) Like the first, I found this chapter tough going. Do I need to re-read it?

A) No, if you managed to build the app, you have made enough progress to handle all of the next chapter. All the blanks in our knowledge will be steadily filled in and replaced with glorious moments of realization as the book progresses.
