Function derive

derive<
    V,
    const Deps extends Variable<any>[],
    Args extends
        {
            [K in string | number | symbol]: Deps[K] extends Variable<T>
                ? T
                : never
        },
>(
    deps: Deps,
    fn: (...args: Args) => V,
): Variable<V>
Creates a derived Variable from multiple source Variables.

Similar to merge but operates on Variables directly rather than Bindings, and returns a Variable instead of a Binding.
Type Parameters
- V
- const Deps extends Variable<any>[]
- Args extends { [K in string | number | symbol]: Deps[K] extends Variable<T> ? T : never }
Parameters
- deps: Deps
  Array of Variables to observe
- fn: (...args: Args) => V
  Function that receives all current values and returns the derived value
Returns Variable<V>
A new Variable containing the derived value
