[MUSIC] 0:00 Hi, I'm Ashley, welcome to this JavaScript practice session on object interaction. 0:09 For this practice session, 0:13 we've been given the challenge of creating a basic library application. 0:15 To do this, we'll use Object Oriented Principles. 0:19 In this practice session, there'll be videos explaining each step of the way, 0:22 followed by opportunities to try the coding on your own. 0:25 A solution will be provided for each coding step, this is just for practice. 0:28 If you're struggling with something, 0:32 you can try to sort it out by using documentation, 0:34 Treehouse's JavaScript syntax glossary or just the Treehouse community. 0:36 But you can also jump straight to the solution, 0:40 there is a tremendous benefit to making an attempt and following along. 0:42
