How to inherit all properties of a type into another type and some more

Question

I have two types one inherits all the properties of other so I rewrite them all on the child. Is there a shortcut way to write this?

type Parent = {
  a: string,
  b: string
}

type Child = {
  a: string,
  b: string,
  c: number
}

Does this answer your question? [Possible to extend types in Typescript?](https://stackoverflow.com/questions/41385059/possible-to-extend-types-in-typescript) — Ben Wainwright, Mar 16 '21 at 16:03

You can do like this :

type Parent = {
  a: string,
  b: string
}

type Child = Parent & { c: number }
