Ask HN: What do you wish more programmers knew about?

I wish more of my colleagues used early returns. I regularly find myself four or five levels of indentation deep because of nested if statements when we could've bailed 30 lines ago and saved the cognitive load.

Yup, it's a shame that they're sometimes taught to be an anti-pattern.

Maintainability matters.

Sooner or later someone else - perhaps under duress - will have to do something with you code.

Assuming everything is obvious is a bad assumption to make.

Kludgy code. Cargo culting. Lack of commenting & docs.
