Check if value exists in enum in TypeScript

Question

I recieve a number type = 3 and have to check if it exists in this enum:

export const MESSAGE_TYPE = {
    INFO: 1,
    SUCCESS: 2,
    WARNING:         


        

Answer 1

enum ServicePlatform {
    UPLAY = "uplay",
    PSN = "psn",
    XBL = "xbl"
}

becomes:

{ UPLAY: 'uplay', PSN: 'psn', XBL: 'xbl' }

so

ServicePlatform.UPLAY in ServicePlatform // false

SOLUTION:

ServicePlatform.UPLAY.toUpperCase() in ServicePlatform // true
