The inheritance between JS objects discards the concept of the prototype and the constructor, and inherits the way the attribute is copied between the literal objects.First, let's write a well-encapsulated inheritance function:function Extend (parent) { var child={}; for (var in parent) { Child[i]=parent[i]; } Child.uber=parent; return Child ;}The function has an argument parent, a new empty child object inside the function, which, like a white artboard, gradually copies

will build it, who will use it, and others will participate in these decisions ("stakeholders").Step 2: Cut down 50%, then chop off the 50%complex systems are always evolved from simple systems. Systems that are very complex from the start are difficult to run, and cannot be patched once a problem occurs. So you have to start by designing a simple system to work with. --John Gaul (John Gall). Most of the great ideas are huge. A huge web site will take tens of billions of dollars to build, and i

. Uber = parent. Prototype; }The method for using this function is as follows:Extend (CAT, animal );VaR cat1 = new CAT ("Da Mao", "yellow ");Alert (cat1.specoes );6. Copy inheritanceIf all attributes of the parent object and the French method are copied to the sub-object, inheritance can also be realized. Function animal (){}Animal. Prototype. Species = "animal ";Function extends (child, parent ){VaR P = parent. Prototype;VaR c = Child. Prototype;For

TNW Chinese station April 8 reportThe software development language of the Android operating system is Java, and over the last few years there has been a long-standing lawsuit between Google (Weibo) and Oracle over copyright in Java. Google is considering Swift as the "first-tier" language for future Android software development, and companies such as Facebook and Uber are starting to pay more attention to Swift's use, according to the latest foreign

means that Google will have higher income. Top Secret Lab . I wonder if you can imagine, in a driverless car, playing Google glasses, that would be a very novel thing, in 2010, Google set up a specialized laboratory for Invention Research, the laboratory is said to be strict confidentiality measures, only the department of researchers can enter, behind each door regret hanging " Be careful with the person behind you "such a warning card." And there

Google search is a natural language processing application, so you will find that the technology is actually changing the world. However, in the author's opinion, natural language processing sti

Professor Yangqiang expressed a high degree of interest and affirmation for the deep exploration and layout of the product-friendly interaction in the field of artificial intelligence business decision-making. At the conference, Professor Yangqiang will deliver a deep lecture on the theme "AI-driven Future enterprise". With the rapid development of art
