1·Functional programming also stretchs the brain, as it makes you think of solving problems by chaining solutions together.
函数式编程还很伤脑筋，因为它让您通过将解决方案链接在一起来考虑解决问题。
2·Method chaining USES return values from methods to relay instruction context, which in this case is the object instance making the first method invocation.
方法链接使用方法的返回值来中转指令上下文，在这种情况下是进行第一个方法调用的对象实例。
3·This is your first choice because it's easy to register (and unregister) event functions, and chaining through multiple registered functions is handled by the browsers.
这是首选的，因为很容易注册（和注销）事件函数，而且可以将浏览器处理的多个已注册函数链接起来。
4·Employ backward chaining to develop the class.
使用逆向链接来开发类。
5·So far, method chaining looks like a simple way to clean up overly verbose syntax, especially method calls that are mostly declarative.
到目前为止，方法链接看起来像一个清理过多繁琐语义的简单方法，特别是最具声明性的那些方法调用。
