AKMA’s Random Thoughts

OK, I'll bite. Did you use this as a chance to explain the concept of compassion, or that of karma?

Enquiring minds and all that...

Well, to be candid, I just said, “Pippa?!” She quickly retracted. Then yesterday, I pointed out that we were the losers as we stood in a couple of twelve-mile traffic jams.

I dunno. I'm sorta with Pippa. One ought to revel in victory--however evanescent--wheneve one can.

Note the new asterisks whenever we reference favoriteNumber, except for that new line right before the return.

These secret identities serve a variety of purposes, and they help us to understand how variables work. In this lesson, we'll be writing a little less code than we've done in previous articles, but we'll be taking a detailed look at how variables live and work.

We can see an example of this in our code we've written so far. In each function's block, we declare variables that hold our data. When each function ends, the variables within are disposed of, and the space they were using is given back to the computer to use. The variables live in the blocks of conditionals and loops we write, but they don't cascade into functions we call, because those aren't sub-blocks, but different sections of code entirely. Every variable we've written has a well-defined lifetime of one function.
