How to make Canvas draw animation

If we have lineTo(50, 100);, How do we animate It drawing ... (50, 100)? Here I have a line drawn already, but it's not animated (don't know how). https://code.sololearn.com/WL7sS6c3HaHJ/?ref=app

Use of setInterval or setTimeout method https://code.sololearn.com/WLNx6w5n923l/?ref=app https://code.sololearn.com/WZLu4j4XT1S8/?ref=app However you should always use requestAnimationFrame method in canvas animation in order to get smoother movement.

setInterval(1000). might work better in your case. you can increment the lines x and y position every second in a for loop. if the drawing needs to slow down you can say like setInterval (1000 / 5)
