Inferring object types through direct values

This code example has a lot of detail:

interface Coordinate {
  latitude: 40.7128;
  longitude: -74.0060;
}

const location: Coordinate = {
  latitude: 40.7128,
  longitude: -74.0060,
};

// The inferred type would have been
// { x: number; y: number; }

Is there a way to utilize type inference in this scenario while also enforcing specific literal values?

Answer №1

Consider using the as const syntax:

const coordinates = {
  latitude: '40',
  longitude: '-73',
} as const; // { latitude: '40'; longitude: '-73'; }
