What a Tool!

Issue #374  (Func Params, CSS/HTML, JSON/DB, Uncats)09/17/20

Previously I've discussed a number of different tips around object and array destructuring in ES6, which make code much easier to read and maintain. Another good suggestion I recently came across has to do with using more than two parameters in a function definition.

It's generally been recommended for more maintainable code to avoid more than a few parameters per function. Of course, this isn't always practical. So it's been suggested that three or more arguments be condensed into a single object:

function doSomething (config) {

pages: 3,
  posts: 10,
  editable: true,
  format: 'markdown',
  archive: false

This is fine and its been used forever, but the one slight problem is that you can't tell from the function head exactly what's expected – even if you know it's a config object.

How much nicer to use object destructuring to do the same thing while keeping the clarity of the object visible in both the function call and function definition:

function doSomething ({ pages, posts, editable, format, archive }) {
  // do whatever with any value...

Try it on CodePen

This time, instead of the ambiguous 'config' object that could be any number of prop/value pairs, I can clearly see what options the function expects without having to examine the code or read any code comments or documentation.

And as a bonus, consider the pre-destructuring example. A linter will tell you if the function uses the object itself, but it won't tell you if all the properties are used (which is what you really want to know). On the other hand, the linter will inform you if all the destructured values are used.

ESLint Errors when destructuring object

This is much cleaner and very easy to read and your linting tool will give you a little help on it too.
