This article mainly introduces "what is the object-oriented of javascript". In the daily operation, I believe that many people have doubts about the object-oriented of javascript. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts of "what is the object-oriented of javascript?" Next, please follow the editor to study!

What is object-oriented?

1. Object-oriented is to decompose the composition problem into multiple objects, and the object is not to complete a step, but to describe the behavior of something in this step of solving the problem.

two。 Object-oriented is a way of thinking.

3 object-oriented is a programming method.

4 object-oriented is not just for a certain programming language.

Second, the difference and relationship between object-oriented and process-oriented?

1. Process-oriented focuses on the steps of solving the whole problem, focusing on local or specific.

2 object-oriented focuses on specific functions, so that an object has such functions, focusing more on the whole.

Advantages of process orientation:

1. The process makes the programming task clear, and the implementation method and the final result are basically considered before development.

two。 High efficiency, process-oriented emphasis on the short and concise code, good at combining data structures to develop efficient programs

3. The process is clear, the specific steps are clear, and it is convenient for node analysis.

Process-oriented disadvantages:

1. It requires in-depth thinking, energy-consuming, low code reusability, poor scalability, and high difficulty in maintenance.

two。 For complex business, the process-oriented module is more difficult and has a high degree of coupling.

Advantages of object orientation:

1. The structure is clear and the program is easy to be modularized, structured and abstract, which is more in line with the human way of thinking.

two。 Encapsulation, which highly abstracts transactions so as to facilitate behavior analysis in the process as well as operation and introspection

3. Easy to extend, high code reuse rate, inheritable, overlay

4. The implementation is simple, the maintenance workload of the program can be effectively reduced, and the efficiency of software development is high.

The disadvantages of object orientation are:

1. Inefficient, object-oriented is highly abstract on the basis of process-oriented, so there are few opportunities for direct interaction with the bottom of the code, so it is not suitable for low-level development, games and even multimedia development.

two。 Complexity, for transaction development, the transaction itself is process-oriented, and excessive encapsulation leads to the increase of the complexity of the transaction itself.

III. Object-oriented implementation

1. There are two main ways of object-oriented implementation: class-based object-oriented and prototype-based object-oriented.

two。 Object-oriented features: encapsulation, inheritance and polymorphism.

3. Class-based object-oriented: Java, C # objects (object) rely on classes (class) to produce.

4. Prototype-based object-oriented: javascript objects (object) are constructed by using prototypes (prototype) from the constructor.

4. Multiple ways to create objects

Basic encapsulation, factory pattern, constructor, prototype object, composition creation.

At this point, the study of "what is the object-oriented of javascript" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
