Time：07-16

function Hoge() {
  ...
  // A and B, both of them are different complicated object value(type).
  return {A, B}
}

I want to describe only A type on below example. How do I get type of only A or B using ReturnType<T>

const A: ReturnType<typeof Hoge>

CodePudding user response：

Using Indexed Access Types, you can get the type of the property A from the return type.

const A: ReturnType<typeof Hoge>['A']
