SQUEEZING LAST BIT OF JAVASCRIPT PERFORMANCE FOR MY AUTOMATION GAME

Summary from the TLDR Web Dev newsletter

An author of a web-based factory automation and economy simulation game shares how they used various performance optimization techniques to reduce the game’s execution time from 21 seconds to 4 seconds. These techniques include replacing strings with small integers, using memoization extensively, and switching to Map/Set data structures when possible. Each optimization is walked through with a corresponding code example.
