For beginners with no basic knowledge, learning JavaScript may be a little difficult. However, if you want to have skills in web development, understanding JavaScript is essential. Below we will introduce you to some methods and techniques for getting started learning JavaScript.

  1. Understand basic syntax

As a programming language, JavaScript has its own syntax rules. Therefore, when learning JavaScript, you need to learn some basic syntax knowledge first. For example, basic data types, variables, operators, conditional statements and loops are all things you need to master.

  1. Learn DOM Programming

An important feature of JavaScript is that it can manipulate elements on web pages. Learning DOM programming allows you to use JavaScript to manipulate web page elements, such as changing text content, modifying element styles, adding and deleting elements, etc. To learn DOM programming, you need to be familiar with the basic structure and operation methods of DOM, including document objects, nodes, events, etc.

  1. Do exercises and projects

The best way to learn programming is to practice. You can deepen your understanding and use of JavaScript by doing some simple exercises and small projects. For example, write a simple calculator, clock, etc.

  1. Learn frameworks and libraries

In addition to basic JavaScript language knowledge, you can also learn some commonly used frameworks and libraries to improve programming efficiency. Such as jQuery, React, Vue, etc. These frameworks and libraries can help you complete complex tasks faster while reducing the amount of code.

  1. Follow the community and blog

Learning JavaScript is a process of continuous learning and self-improvement. There are JavaScript communities and blogs you can follow to learn about the latest development techniques and best practices. Some well-known communities and blogs include MDN Web Docs, Stack Overflow, Medium, and more.

  1. Take online courses

If you want to learn JavaScript systematically, you can take some online courses. Some universities and online education platforms offer free or paid JavaScript courses. By taking courses, you can systematically learn JavaScript knowledge and skills and communicate with other developers.

  1. Participate in programming communities

You can join some programming communities to communicate and learn from other developers. Through the community, you can learn about the latest technology trends, share your knowledge and experience, and get guidance from some programming mentors.

Summary

Learning JavaScript may be difficult for a novice, but as long as you master some basic syntax knowledge, understand DOM programming and frameworks, and do some exercises and projects , follow communities and blogs, and participate in online courses and programming communities, you can quickly get started and master JavaScript programming skills.
