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?

canvas html javascript

Make sure to call beginPath()

function animate (){
 requestAnimationFrame(animate)

  c.clearRect(0,0,canvas.width,canvas.height); 

  c.beginPath();
  c.arc(x,y,40,0,Math.PI * 2,false); 
  c.strokeStyle='rgba(200,0,0,1)';
  c.stroke();

 c.fillStyle ='rgba(0,0,0,1)';
 c.fillRect(x,y,100,100);
 x++


} animate()
