Better Code Monday 09/12/19

Good day! 👋

Here are this week's three coding tips:

Tip #1 - Pure functions

Consider using pure functions when possible. A pure function is great because:
  • It doesn't change things outside of its scope.
  • Focus only on its scope, hence reduces the complexity.
  • More testable as it only depends on its inputs.
Example 👇🏽
Other examples of pure array functions:

Tip #2 - More productive peer-reviews 👩🏽‍💻

When working in a team. You should discuss the coding standards you would like to follow. Once the rules are defined, these must be followed & automated by linters, formatters, and tests.

Recommendation: Run the linters & tests before every commit. If something fails, the commit is aborted.This way, you ensure no rules are forgotten.

For this purpose, I found the npm package husky to be a useful tool. 

This way before the code is submitted for peer-review. All the common issues are already taken care of and you can have a productive peer-review session.

Tip #3 - In case you didn't know

In Javascript, besides the spread operator, you also have the "rest" operator. Here is how it looks like! 👇🏽
Note: Rest operators have to be at the last argument.
