derive

derive(this: Cell<V>, fn: (v: V) => V): this
Read-only same-type view: the RO dual of the endo .lens. For a cross-type view use the typed static Target.derive(src, fn).
Parameters
- this: Cell<V>
- fn: (v: V) => V
Returns this
Inherited from Cell.derive
- Defined in src/core/cell.ts:885

lens

lens(this: Cell<V>, fwd: (v: V) => V, bwd: (target: V, current: V) => V): this
Endomorphic lens. A 2-arg bwd(view, current) consults the current source; a 1-arg bwd(view) reconstructs it from the view alone.
