What is the official name of the key type for the Built-in Object?

There was a built-in type that I used in the past which represented the union of all possible object keys. It was named objectKey or something similar.

Here is an example:

type objectKey = string | number | symbol

Unfortunately, I am drawing a blank on the exact name now. Can anyone help jog my memory?

Answer №1

Its official name is PropertyKey.

declare type PropertyKey = string | number | symbol;
