You can see how the previous version was invalid here:

```
./prog.go:25:9: assignment mismatch: 2 variables but strconv.Itoa returns 1 values
./prog.go:25:25: cannot use "1023" (type untyped string) as type int in argument to strconv.Itoa
```
Because I'm interested in web application development, I used my free time to write this book as an open source version. It doesn't mean that I have a very good ability to build web applications; I would like to share what I've done with Go in building web applications.
For those of you who are working with PHP/Python/Ruby, you will learn how to build a web application with Go.
For those of you who are working with C/C++, you will know how the web works.
I believe the purpose of studying is sharing with others. The happiest thing in my life is sharing everything I've known with more people.
