Javascript optimization techniques (document slimming) have recently been researching Javascript-related technologies. In the Javascript advanced programming, a chapter focuses on the importance of optimizing Javascript code. I believe that many Javascript developers will be

JavaScript is the most popular scripting language in the world, because all of the pages you browse on your computer, mobile phone, tablet, and countless HTML5-based mobile apps, the logic of interaction is JavaScript-driven.To put it simply, JavaScript is an interpreted programming language that runs in a browser.So the question is, why should we learn

Introduction to JavaScript in the first chapter1. A brief history of JavaScriptInvented in 1995 by Netscape's Brendan Eich, JavaScript was originally designed to handle some input validation operations on the client, and since then became a feature of common browsers, and today's use is not limited to simple data validation, but ability to interact with almost any aspect of the browser window and its conte

Javascript object-oriented programming, javascript object-oriented Before learning js object-oriented programming, you must first know what object-oriented programming is. Object-oriented languages all have the concept of classes, through which you can create objects with the same attributes and methods. But js does not have the concept of classes, so the objects in js are different from those in other lang

How to Implement the syntax features of Private Members and the implementation method of private members based on JavaScript, javascript syntax Preface Encapsulation is an essential concept in the object-oriented programming paradigm. In traditional object-oriented languages such as Java and C ++, private Members are an important way to implement encapsulation. However,

In this topic, we will discuss JavaScript testing to check whether the component status and working method meet expectations. We will also introduce a testing method that facilitates the compilation of test cases. The tests mentioned here are of course the use of automated testing methods, which is an important part of software quality assurance (QA. In this topic, we will discuss JavaScript testing to chec

Recently, I have passed some tests to comprehensively parse the JavaScript code execution sequence of web pages in various browsers and record them here. We know that javaScript is an interpreted language, and its execution is top-down, but the understanding of each browser is slightly different, the upstream and downstream of the code, that is, the Program Stream, is crucial to the correctness of the progr

In this article, I will introduce six thinking skills to help you learn JavaScript faster and become a happier and more productive programmer. When we are learning JavaScript or any other coding skills, it is often because of these obstacles: Some concepts may cause confusion, especially when you switch from other languages. Cannot find time (sometimes motivation) for learning. It is easy to forget
