Each block bindings

You can even bind to properties inside an each block.

<input
	type=checkbox
	bind:checked={todo.done}
>

<input
	placeholder="What needs to be done?"
	bind:value={todo.text}
>

Note that interacting with these <input> elements will mutate the array. If you prefer to work with immutable data, you should avoid these bindings and use event handlers instead.
