Similar to "A", "B", and "C", create an object class "a", "B", and "c" in ECMAScript. Correspondingly, the object "a" has a common part of the object "B" and "c. Meanwhile, objects "B" and "c" only contain their own additional attributes or methods.

In A system based on class [class-based], these reusable parts are called class inheritance-put the same part into class A, and then class B and class C inherit from class, you can declare that you have something unique.ECMAScript does not have the concept of a class. However, the concept of reusing [reuse] is no different (in some aspects, or even more flexible than class-) and can be implemented by prototype chain. This inheritance is called dele

In the current implementation, applicationmaster requests all resources on a node and starts the supervisor service. That

In the IPV6 address, any full "0" and All "1" fields are legal unless otherwise excluded. In particular, the prefix can contain a "0" value field, or you can use "0" as the End field.
