In this chapter, we will be discussing regular expression, which is also known as regex or regexp. It is an approach that's designed to define a pattern that can be used to find a sequence of characters in text. This is an extremely useful technique that is supported by many text editors and integrated development environments.

Another topic that will be covered in this chapter is serialization. This is the process of translating an object state into a format that can be stored, such as JavaScript Object Notation (JSON) or Extensible Markup Language (XML).

This chapter covers the following topics:

• Introducing regular expression
• Kotlin and regular expression
• Introducing serialization
• Serialization and Kotlin support
