子标题：Leverage the power of regular expressions to create an engaging user experience
This book starts by exploring what a pattern actually is and how regular expressions express these patterns to match and manipulate user data. You then move on to learning about the use of character classes to define a wild character match, a digit match, and an alphanumeric match. You will then learn to manipulate text and shorten data in URLs, paths, markup, and data exchange, as well as other advanced Regex features.
Finally, you will work through real-world examples, both in the browser and on the server side using Node.js.
