Part 3 / Advanced bindings / This

The readonly this binding applies to every element (and component) and allows you to obtain a reference to rendered elements. For example, we can get a reference to a <canvas> element:

<canvas
	bind:this={canvas}
	width={32}
	height={32}
></canvas>

Note that the value of canvas will be undefined until the component has mounted, so we put the logic inside the onMount lifecycle function.
