Check if a Value Exists in a TypeScript Enum

TypeScript enums are converted into objects like this:

// Enum
enum Vehicle {
  Car = 'car',
  Bus = 'bus',
  Train = 'train',
  Subway = 'subway'

// Converted to the following object
  Car: 'car',
    Bus: 'bus',
  Train: 'train',
  Subway: 'subway'

Therefore, we can use Object.values(...) to check if a value exists in the enum.

const car = Vehicle.Car;

Object.values(Vehicle).includes(car); // true
Object.values(Vehicle).includes('motor'); // false
