003-ts-type-checked.ts

import { isA, typeCheckFor } from 'ts-type-checked';

// Using the typeCheckFor type guard factory 
const isString = typeCheckFor<string>();
const isWebSocketMessage = typeCheckFor<WebSocketMessage>();
  
// Or directly checking a value somewhere in the code
if (isA<string>(value)) return 'Hello String';
if (isA<WebSocketMessage>(value)) return 'Hello Web Socket!';
