Summary
In this chapter, you learned about how JavaScript came to be and where it is today. You were also introduced to object-oriented programming concepts and have seen how JavaScript is not a class-based OO language, but a prototype-based one. Finally, you learned how to use your training environment—the JavaScript console. Now you're ready to dive into JavaScript and learn how to use its powerful OO features. But let's start from the beginning.
The next chapter will guide you through the data types in JavaScript (there are just a few), conditions, loops, and arrays. If you think you know these topics, feel free to skip the next chapter, but not before you make sure you can complete the few short exercises at the end of the chapter.
