What to learn about JavaScript

JavaScript is a dynamic, high-level computer programming language that is often used to add interactivity and dynamic effects to websites, such as form validation, dynamic page changes, games, etc. Let’s take a look at what you need to learn in JavaScript learning.

Basic Syntax

Learning any programming language requires understanding its basic syntax, including data types, variables, arrays, objects, operators, loops, conditional statements, functions, etc. The same is true for JavaScript. We need to learn its basic syntax, master its grammatical features and usage methods, so that we can make good use of JavaScript.

DOM operation

In web pages, DOM (Document Object Model) is a very important part of JavaScript. It parses the HTML documents in the web page into objects, so that HTML, CSS and content can be modified through JS. Learning DOM operations allows us to control web page elements more flexibly to achieve various interactive effects.

AJAX

JavaScript can interact with the server through AJAX technology, such as obtaining data, submitting forms, updating web pages, etc. Therefore, learning AJAX technology allows us to better collaborate with back-end developers to achieve better website functionality and user experience.

jQuery

jQuery is a widely used JavaScript library that simplifies the complexity of DOM manipulation and AJAX requests. Learning jQuery can quickly master the basics of JavaScript, and then better understand the advanced applications of JavaScript.

ES6

ES6 is a new version of the JavaScript standard that introduces many new features, such as template strings, arrow functions, let and const, classes and modules, etc. Being proficient in ES6 can better prepare us for current and future web development needs.

Frameworks and libraries

In addition to learning basic JavaScript knowledge, we also need to learn various frameworks and libraries, such as Angular, React, Vue, Node.js, etc. These frameworks and libraries allow us to develop web applications faster and more efficiently, taking JavaScript to its extreme.

Generally speaking, learning JavaScript is very rich in content and requires us to study patiently and practice diligently. Only with constant practice can we truly master JavaScript and use it to create useful and impressive web applications.
