TypeScript utility for type-safe dynamic key lookup

TypeSafeDynamicKeys.ts

export const myObject = {
  a: 1,
  b: 2,
  c: 3,
};

const ObjectKeys = <Obj extends Object>(obj: Obj): (keyof Obj)[] => {
  return Object.keys(obj) as (keyof Obj)[];
};

ObjectKeys(myObject).map(key => {
  return myObject[key]
});
