Basics - you will learn data types, operators and some other useful things.
Logic - you will learn all you need to know about case statements and loops.

Input/Output - in this section, you will learn to use streams, write to files and more.
Asynchronous programming - finally, you will learn how to improve performance of some tasks, by running them in parallel.
Exercises - Once you are done with everything else, you will get a few exercises to practice what you have learned.In the end of the book, you will find some useful links and advice going forward.
