javascript object oriented programming interview questions

Last time I talked about some advantages and disadvantages of using constructor to implement class inheritance in object-oriented programming using JavaScript. Next, let's talk about the disadvantages of the prototype inheritance law. I hope you can give some suggestions and discuss some of these

What is the hardest part of learning JavaScript?I think it Object 's the hardest. Because JavaScript Object models are unique and different from other languages, beginners are not easy to master.Here is my study notes, I hope to learn this part of you to help. I mainly refer to the following two books:"

Javascript| Programming | objects Object-oriented JavaScript programming should not be unfamiliar to people who have done Web applications, initially to do some simple form validation, basically playing with some technical things.

Before introducing the idea of object-oriented programming in JavaScript, there are several concepts that need to be understood:1. Shallow copy and deep copy: the variables that the program uses in the process of running are variables on the stack and variables on the heap, in the process of assigning objects or variab

In fact, object-oriented thinking is independent of programming languages. For example, in C #, in a static class static method, a series of static functions are called according to procedural development, it is hard to say that this is object-oriented

The core concept of surface Object Programming Technology: encapsulation, inheritance, polymorphism; In some major high-level programming languages, such as: c#,vb.net,java,php, etc. are easy to implement, and if you want to implement polygon object programming in

prototype property ；Replication inheritance has the following advantages:1. It cannot inherit read-only methods and properties of system core objects2. If the object data is very many, so that each copy, the performance is very low;3. Only if the object is actually listed, it is relatively inflexible to traverse the object's members and attributes;4. Copy inheritance is simply an assignment, so if the assi

This article first explained the JavaScript mechanism, and combined with the current popular open source JavaScript framework to explain how to implement object-oriented and inheritance mechanism in JavaScript; This article will cause misunderstanding and Scope in

prototype object (Fun2.prototype) JavaScript is an object-based (object-based) language, and almost all of the things you encounter are objects. However, it is not a true object-oriented pro
