typescript check if value is in enum

Comment

Enum Vehicle {
    Car = 'car',
    Bike = 'bike',
    Truck = 'truck'
}

// becomes:

{
    Car: 'car',
    Bike: 'bike',
    Truck: 'truck'
}

// So you just need to do:

if (Object.values(Vehicle).includes('car')) {
    // Do stuff here
}

check if enum contains value typescript

Comment

// typescript is not executed by browsers, thus typescript's enums don't exist
// at runtime, it's interpreted as a plain js object : it's possible to use
// Object methods like Object.values(), Object.entries(), Object.keys()... 

// this enum
enum MyEnum {
  FIRST="my first value"
  SECOND="second value"
}
// transforms into :
const MyEnumInJs = {
  FIRST:"my first value",
  SECOND:"second value"
}

Object.values(MyEnum) // returns ['my first value', 'second value']
Object.keys(MyEnum) // returns ["FIRST", "SECOND"]
