-### Interface Segregation Principle (ISP)
+### 接口隔离原则 (ISP)
 JavaScript doesn't have interfaces so this principle doesn't apply as strictly
 as others. However, it's important and relevant even with JavaScript's lack of
 type system.
 
+JavaScript 没有接口， 所以这个原则不想其它语言那么严格。 不过， 对于 JavaScript 这种缺少类
+型的语言来说， 它依然是重要并且有意义的。
+
 ISP states that "Clients should not be forced to depend upon interfaces that
 they do not use." Interfaces are implicit contracts in JavaScript because of
 duck typing.
 
+接口隔离原则说的是 “客户端不应该强制依赖他们不需要的接口。” 在 JavaScript 这种弱类型语言中，
+接口是隐式的契约。
+
 A good example to look at that demonstrates this principle in JavaScript is for
 classes that require large settings objects. Not requiring clients to setup
 huge amounts of options is beneficial, because most of the time they won't need
 all of the settings. Making them optional helps prevent having a "fat interface".
 
-**Bad:**
+在 JavaScript 中能比较好的说明这个原则的是一个类需要一个巨大的配置对象。 不需要客户端去设置大
+量的选项是有益的， 因为多数情况下他们不需要全部的设置。 让它们变成可选的有助于防止出现一个“胖接
+口”。
