Converting TypeScript's enum with string values to an array

Question

I have the following enum object in TypeScript:

enum ClassesTypes {
  READY = 'ready',
  DELETED = 'deleted',
}

How can I get from it the following array? ['ready', 'deleted']?

• Tried to use the following code:

const arr = Object.keys(ClassesTypes).map(key => ClassesTypes[key]);

But get the following error:

TS7015: Element implicitly has an 'any' type because index expression is not of type 'number'.>

• When I tried to change it to the following according to this answer

const arr = Object.keys(ClassesTypes).map((key: keyof typeof ClassesTypes) => ClassesTypes[key]);

I get the following error:

TS2345: Argument of type '(key: "READY" | "DELETED") => ClassesTypes' is not assignable to parameter of type '(value: string, index: number, array: string[]) => ClassesTypes'.   Types of parameters 'key' and 'value' are incompatible.     Type 'string' is not assignable to type '"READY" | "DELETED"'
