Enabling rich experiences demands attentive monitoring of input signals emanating from diverse sources. Developers must interpret varying combinations of keyboard strokes and mouse clicks accurately, delivering targeted responses consistently. Plumb the depths of BOM’s input event landscape, distilling nuances into digestible insights backed by concrete examples.

Core Topics Covered:

• Broadcasting raw device activities through standardized interfaces.
• Filtering granular details concerning individual engagements.
• Constructing flexible abstractions accounting for disparate configurations.

Sample Use Case: Building a Virtual Whiteboard

whiteboard.js

const whiteboard = document.querySelector('#whiteboard');

whiteboard.addEventListener('mousemove', handleMove);
whiteboard.addEventListener('mousedown', handleDown);
whiteboard.addEventListener('mouseup', handleUp)…
