It was primarily devised as a strategy for separating user interface logic from business logic.

最初它主要是作为一种分离用户接口逻辑与业务逻辑的策略被设计出来的。

youdao

For example, we might add user interface logic that we want to keep separate from our model, or we might add some classes for performance reasons.

例如，我们可能会添加想与模型分离开来的用户接口逻辑，或者我们可能会出于性能方面的原因而添加某些类。

A common architectural strategy is to layer your system, separating your user interface logic, business logic, system logic, and persistence logic from each other.

通常的构造策略是将系统分层，将用户界面逻辑、商业逻辑、系统逻辑和持久性逻辑彼此分开。

With this approach, all user interface logic and UI state resides entirely within the web browser on the client, and all logic and execution state is kept on the server.

使用此方法，所有用户界面逻辑和UI状态完全驻留在客户端上的Web浏览器中，并且所有逻辑和执行状态都保留在服务器上。
