Clean Functions in JavaScript | Clean Code Tutorial

In this video, we start looking at how to write clean functions.

As with all clean code, functions should be:
⭐️ Searchable
⭐️ Readable
⭐️ Understable

We should also be sure to stick to some other best practices, including:
⭐️ Writing small functions
⭐️ Eliminating boolean flags/dual purpose functions
⭐️ Ensuring functions read top to bottom
⭐️ Using correct function names
⭐️ Limiting parameters
⭐️ Ensuring our functions are DRY (Don't Repeat Yourself)
⭐️ Avoiding side effects

Learning clean code is one of the best career investments you can make. By spending one hour to learn the fundamentals, you get to reap the benefits across all your future code bases. It's 10x the payoff for the effort.
