How to compare Enums in TypeScript

Question

In TypeScript, I want to compare two variables containing enum values. Here\'s my minimal code example:

enum E {
  A,
  B
}

let e1: E = E.A
let e2: E = E.B

if (         


        

Answer 1

The only thing that worked for me (in typescript 2.2.1) was this:

if (E[e1] === E[e2]) {
  console.log("equal")
}

This compares the strings representing the names (eg. "A" and "B").
