Elixir is a dynamic programming language. So, we don’t declare the type of each variable. It depends on the value it holds at each moment. In this lesson, we’ll learn more about Elixir’s basic data types: integers, floats, booleans, atoms, strings, lists, and tuples. Below is the description of available data types in Elixir.

Built-in types

Elixir’s built-in types are as follows:

  • Value types:
    • Arbitrary-sized integers
    • Floating-point numbers
    • Atoms
    • Ranges
    • Regular expressions
  • System types:
    • PIDs and ports
    • References
  • Collection types:
    • Tuples
    • Lists
    • Maps
    • Binaries
