todoList中刪除操作 onClick = {e => store.removeTodo(todo)}為什么一定要這樣寫？
<span?onClick={?this.handleRemoveClick(todo)}>=>?X</span>handleRemoveClick?=?(todo)=>{
????this.props.store.removeTodo(todo)
}會有一個這樣的錯誤提示
Warning: Cannot update during an existing state transition (such as within `render`). Render methods should be a pure function of props and state.
這是為什么？
