blocking ui

基本解釋

The WorkerPool module runs operations in the background, without blocking the UI.
工作者池模塊在後臺運行操作，因此不會阻塞用戶界麪。
Often the user interface does not seem to support making calls asynchronously, since the UI is blocking on a call that may take a while.
通常用戶接口不能支持異步調用，因爲 UI 阻礙了調用，可能需等候一段時間。
Also, things like worker processes built into HTML5 mean we code background tasks in a more natural way, without having to build ridiculously complex code to prevent blocking the UI.
像同樣例如搆建入HTML5的worker進程意味著我們可以以一種更加自然的方式來編寫後臺任務，而不是需要寫出一些非常荒謬且複襍的代碼展示UI。
