Control Flow

For example, with lists, a simple map is inefficient as it always maps the entire array.

\<For>

Simple referentially keyed loop. The callback takes the current item as the first argument:

<For each={state.list} fallback={<div>Loading...</div>}>
  {(item) => <div>{item}</div>}
</For>

The optional second argument is an index signal:

<For each={state.list} fallback={<div>Loading...</div>}>
  {(item, index) => (
    <div>
      #{index()} {item}
    </div>
  )}
</For>

\<Show>

The Show control flow is used to conditional render part of the view: it renders children when the when is truthy, an fallback otherwise. It is similar to the ternary operator (when ? children : fallback) but is ideal for templating JSX.

<Show when={state.count > 0} fallback={<div>Loading...</div>}>
  <div>My Content</div>
</Show>

Show can also be used as a way of keying blocks to a specific data model. Ex the function is re-executed whenever the user model is replaced.

<Show when={state.user} fallback={<div>Loading...</div>}>
  {(user) => <div>{user.firstName}</div>}
</Show>
