Today, it has evolved to become the largest platform on the web and is used on about 20% of all the websites on the Internet.
There are a couple of reasons WordPress has gained so much popularity over the years.

Another reason WordPress has been so successful is the fact that it is an extremely flexible CMS and can be used to power all different types of websites. Developers are constantly exploring innovative new ways to use the software, including using it to build web applications, which is the focus of this book.
