In this chapter, you learned about the JavaScript syntax. We discussed the JavaScript variables and how to assign a value to a variable. You learned how to comment on the code. You now know why commenting is important. You finally learned an important topic: operators and operations. JavaScript, without using operators and logical functions, will not be so rich nowadays. Therefore, learning about the logical operations is the key to gain good knowledge of JavaScript.

I would like to suggest you to practice all the code in this chapter at home. You just type them on the console, avoid copying and pasting the codes. This will hamper with your learning. As a programmer must have a good typing speed, copying and pasting the codes will not improve this skill. You may face problems in typing codes; however, you will learn.

You can solve any arithmetic problem using JavaScript. You can also check whether your logic is true or false on console. If you can do this, we can move on to the next chapter, Chapter 3, Introducing HTML and CSS, where you will learn about HTML, CSS, and so on.
