How to Get a Typescript Enum from a String

Enums in TypeScript are very helpful for defining a set of values. To turn a string into an enum, you need to cast it so TypeScript understands the string you have provided exists in the Enum.

To do this, you can do the following:

enum Animal {
  Cat,
  Dog,
  Mouse,
}

const name = 'Cat'
const animal: Animal = Animal[name as keyof typeof Animal]

This works on all modern versions of TypeScript. Here, Name is being cast to a value existing within Animal.
