How to get all the values of an enum with typescript? [duplicate]

Question

You have to filter out the numeric keys, either via Object.values or Object.keys:

const colors = Object.keys(Color).filter((item) => {
    return isNaN(Number(item));
});
console.log(colors.join("\n"));

This will print:

Red
Green
Blue

A TypeScript enum will transpile in the end into a plain JavaScript object:

{ 
  '0': 'Red', 
  '1': 'Green',
  '2': 'Blue',
  Red: 0,
  Green: 1,
  Blue: 2
}

So you can use the numeric index as key to get the value, and you can use the value to lookup its index in the enum:

console.log(Color[0]); // "Red"
console.log(Color["0"]); // "Red"
console.log(Color["Red"]) // 0
