Examples

Example 1

class One {
  a() {}
  b() {}
  c() {}
}

const methods = ["a", "b", "c"];

const one = new One();

one[methods[0]]();
// Element implicitly has an 'any' type because expression of type 'string'
// can't be used to index type 'One'.(7053)

one[methods[0] as MethodOf<One>]();
// OK
definition: [K in keyof Object]: Object[K] extends Func ? K : never[keyof Object]
