Chapter 2. MongoDB through the JavaScript shell

The previous chapter hinted at the experience of running MongoDB. If you’re ready for a more hands-on introduction, this is it. Using the MongoDB shell, this chapter teaches the database’s basic concepts through a series of exercises. You’ll learn how to create, read, update, and delete (CRUD) documents and, in the process, get to know MongoDB’s query language. In addition, we’ll take a preliminary look at database indexes and how they’re used to optimize queries. Then we’ll end the chapter by exploring some basic administrative commands, and I’ll suggest a few ways of getting help as you continue on. Think of this chapter as both an elaboration of the concepts already introduced and as a practical tour of the most common tasks performed from the MongoDB shell.
