A magic type.
The Dynamic type is a type with a special behavior. Through this chapter you will learn why, how you can use it, and also what you should pay attention to. Understanding the Dynamic type is a key point in mastering haXe.
We have already been introduced to haXe's typing system. But in this chapter we will learn about something new in this typing system: the Dynamic type. The Dynamic type is a type that introduces a very special behavior that we will now study.
In this chapter we will:
- Use Dynamic variables
- Learn about Dynamic's pitfalls
- Learn about the parameterized Dynamic class
- Implement Dynamic in a class
- Learn about the use of properties in classes
- Implement properties in classes
Let's get started.
