精读《React Conf 2019 - Day2》

[Sliect]

函数式编程里的例子应该是这个意思

const Store = ({ state, render }) => ({
    state,
    render,
    extend: (f) =>
      Store({ state, render: (state) => f(Store({ state, render })) }),
    extract: () =>  render(state),
  });

  const App = Store({
    state: { msg: "World" },
    render: ({ msg }) => <p>Hello {msg}</p>,
  });

  App.extend(({ state, render }) =>
    render(state.msg === "World" ? { msg: "ReactConf" } : state)
  ).extract();
