Over the past few years I’ve become far less enamered with “clean code”. For a little while, I started to think that it didn’t matter at all. What mattered was solving problems — the faster the…

Explore essential principles for writing better, cleaner code. The author shares insights on effective code practices, emphasizing that functions should perform one task and maintain a consistent return type. Highlighting the value of code readability, abstraction, and functional programming concepts such as map-reduce, the guide provides practical examples to illustrate these points.

A Few Unshakable Principles for Writing Better Code

Falling out of love with “Clean Code”

Functions Should Return One Type of Thing — Or Nothing.

Maintain The Current Level of Abstraction

Everything is a Map-Reduce (Be Declarative)

<p>“Clean Code”: hide throw(error) in subfunctions with no hint in the name.
If I see two function calls directly beneath each other, I expect them both to run, not for somewhere ((deeply) nested) inside the first the program to exit.</p>


<p>One pattern I like is the two-channel function design where the input and output contain an “error” variable to indicate that something went wrong. Can short circuit if the input contains an error, and the caller can check for an error in the output instead of <code>null</code>. Pretty nice pattern.</p>
