ReactJS 구성 요소는 어떻게 서로 효과적으로 통신합니까?

// Filters.js
handleChange = () => {
  const value = this.input.value;
  this.props.updateFilter(value);
};

// List.js
handleFilterChange = (value) => this.setState({ filter: value });
<Filters onChange={this.handleFilterChange} />

// Parent.js
filterChange = (value) => this.setState({ filter: value });

// Filters.js
render() {
  const { filter, updateFilter } = this.props;
  return <input value={filter} onChange={updateFilter} />;
}

// List.js
render() {
  const { filter, items } = this.props;
  return <ul>{items.filter(item => item.includes(filter)).map(...)}</ul>;
}

// GlobalEventEmitter.js
events = {};
on = (event, cb) => events[event] ? events[event].push(cb) : events[event] = [cb];
emit = (event, ...args) => events[event] ? events[event].forEach(cb => cb(...args)) : null;

// ComponentA.js
emit("customEvent", { ... });
componentDidMount() {
  on("customEvent", (payload) => this.setState({ ...payload }));
}

// ComponentB.js
emit("customEvent", { ... });
componentDidMount() {
  on("customEvent", (payload) => this.setState({ ...payload }));
}
