Proposal: Overwrite<Obj, Props>

[rattrayalex]

Roughly this:

type Overwrite<Obj extends {}, Props extends {}> = Omit<Obj, keyof Props> & Props;

To be used like so:

type Foo = {
  a: string,
  b: number,
}
type Bar = Overwrite<Foo, {
  b: string,
}>
// Bar == { a: string, b: string }

This exists in utility-types.

Isn't this the same as Merge?

Ah, so it is! My mistake. Thank you!
