Code Smell Alert: A common code pattern that I see is where the if/else logic and the if conditional is backwards. I call this the “if/else backwards code pattern.” This code pattern makes the code less readable, which decreases its quality. There are two clues to let you know that you have stumbled into this pattern: The if conditional is set off of a false state. Typically you’ll see a not operator (!) as your clue. The if logic is setting a default state. But that is the job of the else. Smelly Version This is the smelling code pattern: […]
Smelly Code: the “if/return true/false” Code Pattern
When doing a conditional expression, it’s a smelly code pattern to then return true or false. Why? The conditional expression already returns a true or false state. Therefore, you do not need to be so verbose and hardcode a boolean return. Here is the smelly code pattern: Refactor this code down to one line to make it more readable. It’s less code too (skinny). Strive to reduce your code and make it more simple. If you see this pattern in your code, then refactor it. Remember, you want your code to be as skinny (as few lines) as possible.
