After reading lesson 25, you’ll be able to
In this lesson, you’ll learn about working with binary file data by using Haskell’s ByteString type. ByteString allows you to treat raw binary data as though it were a regular string. To demonstrate the use of ByteString, you’ll focus on a fun project requiring you to manipulate binary file data. You’ll create a simple command-line tool that will allow you to create glitch art, like that in figure 25.1.
