How lazily instantiated classes reduced my game engines' reset times by half
Read OriginalThe article details a performance optimization in a custom JavaScript game engine. The author's 'ObjectMakr' module originally instantiated hundreds of dynamic class objects at startup, causing slow reset times. By shifting to lazy instantiation—only creating classes when they are actually needed—reset time was cut from ~700ms to ~300ms, with class creation time dropping from 400ms to 1ms. The piece concludes with lessons on minimizing unused work and the trade-offs of building an engine from scratch.
