生产力技术(四):#DEFINE 和文档查看器 尽管N 多人苦口婆心的灌输 OOP 的设计理念,但是,仍旧有 M 多人我行我素。即使在 OOP 的设计理念下,在一些特定的情况下,也免不了有较长的代码。 每当不得不写长长的代码时,我经常使用下面的方法来尽可能的提高代码的可读性和易维护性。 这个方法,就是使用文档查看器...
Python is an object-oriented programming language.Object-oriented programming(OOP) focuses on creating reusable patterns of code, in contrast to procedural programming, which focuses on explicit sequenced instructions. When working on complex programs in particular, object-oriented programming lets you reus...
Object-Oriented Programming (OOP)is a fundamental programming paradigm used by nearly every developer at some point in their career. But at the beginning of the education of new developers, we must answer the following questions: 1.What is Object-Oriented Programming? 2. What problems can be so...

最近一段时间学习extjs的源码,extjs的主要是oop编程,因此对于extend和define的应用就显得很重要了,这里先补充一些基础知识: 1 new 运算符的内部机制 2 constructor 和 prototype new 运算符内部机制: When the [[Construct]] property for a Function object F is called, the following steps are taken: ...
Creating an Object If you consider an OOP JavaScript world, almost everything is an object. When it comes to object creation, I used to use one of the following three methods: var beautifulObject = {}; // OR var beautifulObject = Object.create( Object.prototype ); //OR var beautifulObj...
Javascript是一种基于对象(object-based)的语言,你遇到的所有东西几乎都是对象。但是,它又不是一种真正的面向对象编程(OOP)语言,因为它的语法中没有class(类)。 那么,如果我们要把"属性"(property)和"方法"(method),封装成一个对象,甚至要从原型对象生成一个实例对象,我们应该怎么做呢?
