Typescript syntax related

Question

I am starting to develop applications using typescript. I had come across a code snippet where I couldn't understand the line marked within ** <> **. Anybody please throw some light.

export const applyRoutes = (routes: Route[], router: Router) => {
  for (const route of routes) {
    const { method, path, handler } = route;
    **(router as any)[method](path, handler);**
  }
};

Answer 1

(router as any) tells typescript that regardless of what it thinks the types are, it should treat router as having type any . In other words, it turns off type checking.

router[method](path, handler) means "access the method property on router , then call it passing in path and handler ".
