Programmers urged to 'push ifs up and fors down' to simplify code

Why it matters for readers: Shows a practical rule programmers use to make code easier to reason about and faster.

The idiom suggests centralizing branching by moving conditional logic (ifs) to the caller or higher-level function.1
Loops and bulk operations (fors) are recommended to be pushed down into tight, branch-free code for performance and clarity.1
TigerBeetle's 'Tiger Style' document is one source promoting the recommendation.1
Matklad (a noted blogger) has written about the principle and its benefits for code structure.1
The topic was discussed and upvoted on Hacker News, indicating community interest.1
