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?

To clear the Canvas, you can use the clearRect() method. This method performs pretty well than others for clearing the canvas (such as resetting the width/height, destroying the canvas element and then recreating it, etc..) const context = canvas. getContext('2d'); context.
The arc() method creates an arc/curve (used to create circles, or parts of circles). Tip: To create a circle with arc(): Set start angle to 0 and end angle to 2*Math. PI. Tip: Use the stroke() or the fill() method to actually draw the arc on the canvas.
There is no clearArc however you can use Composite Operations to achieve the same thing
context.globalCompositeOperation = 'destination-out' According to MDC the effect of this setting is
The existing content is kept where it doesn't overlap the new shape.

So any filled shape with this mode on will end up erasing current canvas content.
