Section 1 - Tutorial

The first section of this book contains two chapters:

• A tutorial on pure Haskell development: no side effects.
• A tutorial on impure Haskell development: dealing with the world (I/O, network access, database access, etc.)

After working through these two tutorial chapters you will have sufficient knowledge of Haskell development to understand the cookbook examples in the second section and be able to modify them for your own use. Some of the general topics will be covered again in the second book section that contains longer example programs.
