Insights & Quick Tips
Quick tips, master tips, and insights just for you.
How Many Inline Comments Should Your Code Have?
What's the limit for inline comments, and how can you minimize them? Let's look at a bad and a good example of inline comments, and how they're chances to improve your code.
Quality Code Tip: Views are for HTML – Not Your Business Logic
In today's quality code tip, you will learn about removing the HTML from your business logic and putting it into a view file. In programming, you want to separate out your code by its intent and purpose. Let's discuss the what, how, and why of view files. (Side note: I'm showing you the actual code on this website which is powered by Genesis.
if/else Backwards Code Pattern – Code Smell
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.
Code Tip: Return Early
Within a function, when you are done processing, i.e. the conditions are set, then return early. Don’t wait until the end of a function to return. Don’t wrap up your code in conditional expressions when you could have just returned early if the conditions were not met. Why? It makes your code hard to read. The guideline is this: When done, return. Otherwise, continue processing.
Code Tip: Purposeful Naming
Let’s talk about naming of variables, functions, etc. in your code. In this video, you will learn some handy guidelines on naming by intent to let your code express what it’s doing, why it exists, how to use it, and what to expect from it. This tip is valid for all programming regardless of the language or technology.
