apply[A](a: A): UndefOr[A]
Explicitly upcasts an
A
to ajs.UndefOr[A]
.Explicitly upcasts an
A
to ajs.UndefOr[A]
.This method is useful in some cases to drive Scala's type inference. For example, when calling a method expecting a
js.UndefOr[js.FunctionN]
as shown below:def foo(f: js.UndefOr[js.Function1[Int, Int]] = js.undefined): Int = ??? foo((x: Int) => x + 1) // compile error (requires 2 chained implicits) foo(js.defined((x: Int) => x + 1)) // compiles // 2.12+ only: foo(js.defined(x => x + 1)) // compiles as well
