Summary
This chapter began with information about Redis's history and some of its design decisions. We explained how to install Redis and demonstrated that the redis-cli tool can be a very powerful tool for debugging and learning Redis.
Some examples in this book that require a programming language are implemented in Node.js. Therefore, a quick reference to JavaScript's syntax and Node.js installation were shown.
Redis data types is an extensive subject, and it has been split into two chapters. This chapter explained how Strings, Lists, and Hashes work. The next chapter will cover Sets, Sorted Sets, Bitmaps, and HyperLogLogs and give practical examples.
