Document all functions, their arguments and return values, and also any interesting or unusual algorithm or technique. Think of the comments as hints to the future readers of the code; the readers need to understand what your code does without reading much more than just the comments and the ...

There was a lot of pre-learning I had to do to even get started understanding what I was working with, since I had never learned about computer science basics before. So I wroteUnderstanding Bits, Bytes, Bases, and Writing a Hex Dump in JavaScriptwhich goes over much of that. ...
That’s where unit testing comes in. And we’ll have a very hard timewriting unit testsuntil we startwriting testable JavaScript. Unit vs. integration: what’s the difference? Writing integration tests is usually fairly straightforward: we simply write code that describes how a user interacts wit...
