MapSignal() function

Maps the values emitted by a signal to a renderable function and returns a new renderable function.

While it is tempting to use MapSignal for its simplicity, it is important to remember that the renderable function returned by MapSignal will be re-rendered every time the signal emits a new value.

In other contexts link Ensure or OneOf, the renderable function is only re-rendered when the signal changes to a state that requires a different renderable function.

Signature:

MapSignal: <T>(value: Value<T>, fn: (value: T) => TNode) => Renderable

Parameters

Parameter	Type	Description
value	Value<T>
fn	(value: T) => TNode	The function to map the signal values to a renderable/TNode.

Returns: Renderable

• A new renderable function that represents the mapped signal.
