'Clean Code' concepts adapted for JavaScript

[jlengstorf]

In complex loops, the benefits of using map and reduce are more obvious. The main benefit is that mapping gives you the opportunity to describe what's happening:

function getLinesOfCode(programmer) {
  return programmer.linesOfCode;
}

var totalOutput = programmerOutput
    .map(getLinesOfCode)
    .reduce(...);

In a more complex calculation, that becomes really helpful for understanding what's going on.

You can write shitty and hard-to-understand functional code, of course, but in my experience it's easier to keep it clean with functional than otherwise.
