What will you learn?

You'll make HTTP requests and parse HTML to generate reports that can easily marshaled to standard output or a file. If you're interested in getting a job doing data analysis, this project will teach you how Go can be used to build a command-line application.

Building the same project but in Go solidified my love for Go. Handling concurrency in Go is so much more elegant.

This project was really fun. It was not easy but I understood everything. My favorite part was the chapter on concurrency--my first exposure to controlled concurrency.
