Standard Data Types

In the first half of this chapter, we study data types that OCaml has built-in and are likely to feel familiar from many other languages. Because of that familiarity, we call them standard data types. They include:

• lists and tuples, which might feel similar to Python;
• records and variants, which might feel similar to struct and enum types from C or Java.

We also take a detour into unit testing.
