Canvas API

ELI5 — The Vibe Check

The Canvas API gives you a blank rectangle and says 'draw whatever you want with code.' It's like MS Paint but controlled by JavaScript. Great for games, charts, image manipulation, and making your designer colleagues nervous because there are no design files.

Real Talk

The HTML Canvas API provides a 2D drawing surface manipulated via JavaScript. It supports paths, shapes, text, images, pixel manipulation, and compositing. Canvas renders as a bitmap, making it ideal for dynamic graphics, games, and real-time visualizations but not inherently accessible.

Show Me The Code

const ctx = canvas.getContext('2d');
ctx.fillStyle = '#2563eb';
ctx.fillRect(10, 10, 150, 80);
ctx.strokeText('Hello Canvas', 20, 55);

When You'll Hear This

"Use Canvas for the signature pad — SVG would be overkill" / "Canvas is fast for pixel manipulation but you lose DOM accessibility"
