What is the Built-in Object Key type called?

Question

I remember previously using a built in type that is the union of all possible object keys, and it was name objectKey or something similar.

For example:

type objectKey = string | number | symbol

However, I can’t remember the specific name now. Does anyone know what it is named?

Answer 1

It is called PropertyKey.

declare type PropertyKey = string | number | symbol;
