How can I clear an arc or circle in HTML5 canvas?

Question

I found that there\'s a clearRect() method, but can\'t find any to clear an arc (or a full circle).

Is there any way to clear an arc in canvas?

Here's an updated fiddle for you too (uses clearRect): https://jsfiddle.net/x9ztn3vs/2/

It has a clearApple function:

block.prototype.clearApple = function() {
    ctx.beginPath();
    ctx.clearRect(this.x - 6, this.y - 6, 2 * Math.PI, 2 * Math.PI);
    ctx.closePath();
}
