如何在 TypeScript 中描述这个对象的形状？

Question

The object looks like a mixture of dictionary and regular JavaScript object:

var obj = {
  'dynamic prop1': { },
  'dynamic prop2': function () { },
  'dynamic prop3': function () { },
  'dynamic prop4': function () { },

  func: function() {},
  prop: null
};

The majority of the properties assigned to object will be represented by string-based ('dynamic prop') properties and will contain either object or function.

Additionally it will contain two additional properties: prop and func.

This is some text so it's not a code-only answer.

interface MyObjType {
  [key: string]: (() => void) | { maybeYouHaveSomePropertiesToDeclare?: string };
  func(): void;
  prop: any;
}
