Non-blocking UI

大家都知道non-blocking I/O;类似的概念:non-blocking UI。打开facebook网站或者app,在等待数据加载的过程中,大家看到的不是老套的spinner,而是呼之欲出的界面,相当responsive。 A non-blocking interface should feel fast, responsive and continuous, regardless of network speed. Any action such as loading a new page or clicking a button should have an immediate reaction, and should never be left in limbo.
