One-time proficient in the principle of javascript prototype/inheritance/constructor/class (below)

In the last part, we explained the principles of front-end concepts such as constructors and prototypes, and learned how to share methods between instances through the prototype of the constructor. In the next part, we will mainly look at how to implement the es6 class and the inheritance of the class. Same as the previous article, the focus is on the principles behind it. Only when we understand why we have to design this way can we truly say [Proficient]. If you read the second part very hard,

Talking about the browser http caching mechanism

The analysis of the browser's http cache can be regarded as a cliche, and a good article will appear every once in a while. The principle is almost a must-test question in interviews for major companies. The reason why I wrote such an article is because I have been working on new technologies recently, I want to "return" to the basics, and I hope to summarize it in more detail. So do you still need to read this article? You can try to answer the following question: When we visit the Baidu homep

Defects of javascript language number operation

Preface Anyone who has gotten started with js knows that the mathematical operations of js are flawed. Of course, this problem does not only appear in Javascript. Almost all programming languages use IEEE-745 floating point number notation. Any use The programming language of binary floating-point numbers will have this problem, but in many other languages, methods have been encapsulated to avoid the problem of precision. JavaScript is a weakly typed language, and there is no such thing as floa

How to implement a mobile account app

Some time ago, I was very interested in the implementation details of the account-type apps, so I wanted to implement a minimized viable product by myself. Of course~Since it is a product under the MVP mode, it only realizes the "function", but in some places where I particularly want to "plagiarize", I also put a little effort to pursue UI performance.

How does Vue Xiaokai Bookkeeping (1.03) convey the information of repeated tags?

I wrote a model about modifying TagList and added a create method to the model. Prepare to use the error reporting style first. If the created label has been repeated before, an error will be reported. Note: The above flag determination method uses: Array.prototype.some(function) The some method passes a function inside. This function traverses all elements in the array. If there is an element that satisfies the following formula, it returns true, otherwise it returns false. The sixth act I wrot

Getting to know https

Why use https? The difference between https and http is actually the difference between an encryption and a non-encryption. Why should we encrypt? Because the content we transmit is in full plain text on the http protocol, it is very easy to be seen by others (typically ARP spoofing), so the login account, login password and other information in the web page will undoubtedly be exposed. The https protocol will encrypt the transmitted content, even if it is seen by other people, it does not matte

What is a coroutine By convention, this article should talk about what a coroutine is, rather than anxiously start talking about the details of the implementation, not to mention the fact that the implementation of a coroutine is not very complicated. But there are too many articles about what a coroutine is. There are some in one language, some are false, and even more random. What is in the word is like
