How can I use the HTML5 canvas with requestAnimationFrame?

You can use the HTML5 canvas along with requestAnimationFrame to create smooth animations. First, set up your canvas in HTML, then use JavaScript to draw on it.

Can you show me a simple example of this?

Sure! Here's a basic example:

const canvas = document.getElementById('myCanvas');
const ctx = canvas.getContext('2d');

let x = 0;

function draw() {
    ctx.clearRect(0, 0, canvas.width, canvas.height);
    ctx.fillStyle = 'blue';
    ctx.fillRect(x, 50, 50, 50);
    x += 1;
    requestAnimationFrame(draw);
}

draw();

What does requestAnimationFrame do in this context?

requestAnimationFrame tells the browser that you want to perform an animation and requests that the browser calls a specified function to update an animation before the next repaint.
