1. ObjectObjects are one of the basic concepts of object-oriented programming. You only need to look at this name and you will know it. In our familiar object-oriented languages, such as Java or C ++, there are similar object defi
Basic javascript programming objective Object-Oriented Programming Javascript is an interpreted language, and there is no significant difference between compilation and runtime. Therefore, a more dynamic method is required.
JavaScript is an interpreted language, and there is no obvious difference between compile-time and run-time, so a more dynamic approach is needed. JavaScript does not have a formal class concept, and we can use it to create new object types at run time, and we can change the properties of existing objects at any time.JavaScript is a prototype-based
Recently, I was looking at the JavaScript advanced programming design (the third edition). The object-oriented chapter has more than 20 pages, and I went back and forth for three or five times. The results of each reading were different. The first time I went over it, I was confused, as a result, when I went to bed at

In the meantime, I showed you how to implement it. It also explains how to detect rela

constructor, and by initializing the prototype in the constructor (only if necessary), while preserving the advantages of using both constructors and prototypes. In other words, you can determine whether a prototype needs to be initialized by checking that a method that should exist is valid.Parasitic constructor modeIf the above methods are not applicable, parasitic patterns can be applied. The core idea of this pattern is to create a function that simply encapsulates the code that creates the
