How to make a lightweight game?

Question

JavaScript

I am creating games on js, I am a beginner. I wanted to ask a question how to make a game on js canvas more lightweight and more optimized? I would like to make games that would run and not load the computer with a running browser like this.

Answer 1

JavaScript? To not load? No way.
Seriously, try to write concise code, fewer unnecessary variables, optimize functions. You could write a whole book here.

Answer 2

Simplify the game codes to a minimum so that there is no water and crap.
