Select bindings

We can also use bind:value with <select> elements. Update line 24:

<select bind:value={selected} on:change="{() => answer = ''}">

Note that the <option> values are objects rather than strings. Svelte doesn’t mind.

Because we haven’t set an initial value of selected, the binding will set it to the default value (the first in the list) automatically. Be careful though — until the binding is initialised, selected remains undefined, so we can’t blindly reference e.g. selected.id in the template.
