In this level, we touched on several new topics: what literals are, what escaping is, and why escape sequences came into existence. And also we continued to get to know classes. This time around our agenda featured the String class, as well as the nuances of working with strings. Before moving on, make sure you've got a solid understanding of all this.

You'll gradually learn how to escape characters, even if it seems at present that there are too many rules. It doesn't hurt to read something extra on the topic. For example, there's this helpful article. You can also add it to your bookmarks and periodically take a peek until you no longer need it!
