Crafting Code

Here's the thing. Computers are nothing more than really fast light switches. On & off millions of times per second. All it cares about is ones & zeroes.

So when it comes to code, and more specifically crafting code, who are we really writing code for?

We're writing it for ourselves, our teammates or our customers - basically other humans. We're using code to express ideas, human ideas in terms of a computer language. As developers, we're tasked with creating sets of instructions to be carried out by our dumb servants to execute these ideas.

If the computer doesn't particularly care about code (other than a clean compile) - what are some of the tools we can use to craft our code for human consumption?
