map2<A, A2 extends A, B, B2 extends B, C> static method

Option<C> map2<A, A2 extends A, B, B2 extends B, C>(
  1. Option<A2> fa,
  2. Option<B2> fb,
  3. C fun(
    1. A a,
    2. B b
    )
)

Implementation

static Option<C> map2<A, A2 extends A, B, B2 extends B, C>(Option<A2> fa, Option<B2> fb, C fun(A a, B b)) =>
  fa.fold(none, (a) => fb.fold(none, (b) => some(fun(a, b))));
