JavaScript Input Buffering: a simple project to show delayed keyboard events

This article presents a JavaScript tutorial on creating an input buffer to visualize delayed keyboard events. It explains core concepts for game developers, such as handling keydown/keyup events, avoiding repeated events, using performance.now() for timing, and building an update loop with requestAnimationFrame. The project includes a live demo with commented source code.
