The Rule of Least Power #ROLP
summary
Argues for picking the least-powerful way that still solves the problem and shows concrete swaps: JSON instead of executable JavaScript for data, string methods over regex for simple checks, Math.max(...arr) over reduce to get a max, and object spread or Object.assign instead of reduce-based merges. Demonstrates three depowering techniques — abstraction (small helper like sum), convention (only use map/filter/reduce when returning their value), and types/destructuring to limit scope — with code comparisons and readable-before-powerful counts.
