In this chapter, we look at exceptions in JavaScript. They are a way of handling errors. We’ll need them for the next chapter.

In this blog post, we discuss Oracle’s trademark of the word “JavaScript”:

• What are the problems caused by that trademark?
• How can we fix those problems?

In this chapter, we learn how to create plain objects with properties. We use them to create a simple flash card app.

So far, all of our JavaScript code resided in a single file – be it an .html file or a .js file. In this chapter, we learn how to split it up into multiple files. And how to automatically test if the code we write is correct.

In this chapter, we run a web server on our own computer and use it to serve a web app.

In this chapter we explore two topics:

• A shell is like browser console, but for the operating system instead of for JavaScript. It helps us with programming by running the tools (programs) we need to get things done.
• Node.js is a program that lets us run JavaScript code outside browsers – which we can use for a variety of things.

In this chapter, we learn how to do things repeatedly in JavaScript.

In this chapter, we learn about tools for only running a piece of code if a condition is met: truth values (booleans), comparisons and if statements.

In this chapter we look at one way of storing more than one value in a variable: arrays.

In the last chapter, we worked with numbers. In this chapter, we’ll work with text and write our first applications.
