What is an example of an animation?
For instance, moving along a complex path, with a timing function different from Bezier curves, or an animation on a canvas. An animation can be implemented as a sequence of frames – usually small changes to HTML/CSS properties. For instance, changing style.left from 0px to 100px moves the element.

Overview

•• Since we're using JavaScript to control elements, it's also very easy to make (interactive) animations. In this chapter we will take a look at how to do some basic animations. developer.mozilla.org

Basic animation steps

These are the steps you need to take to draw a frame: 1.Clear the canvas Unless the shapes you'll be drawing fill the complete canvas (for instance a backdrop image), you need to clear any shapes that have been drawn previously. The easiest way to do this is using the clearRect() method. 2.Save the canvas state If you're changing any setting (such as styles, transformations, etc.) which affect the canvas state and you want to make sure the original state is used each time a frame is drawn, you need to save that original state. 3.Draw animated shapes The step where you do the actual frame rendering. developer.mozilla.org

Controlling an animation

Shapes are drawn to the canvas by using the canvas methods directly or by calling custom functions. In normal circumstances, we only see these results appear on the canvas when the script finishes executing. For instance, it isn't possible to do an animation from within a for loop. That means we need a way to execute our drawing functions over a period of time. There are two ways to control an animation like this. developer.mozilla.org
