Elixir has several core data types, including integers, floats, atoms, booleans, strings, lists, tuples, maps, and structs. Each type serves different purposes in data handling.

Elixir provides a rich set of data types that form the foundation of the language and facilitate effective data manipulation. Understanding these data types is crucial for writing efficient and idiomatic Elixir code. The core data types include integers, which are whole numbers, and floats, which represent decimal values. Atoms are constants with a name, useful for representing unique values, while booleans are used for true/false evaluations. Strings in Elixir are represented as binaries, which are efficient for handling text data. Lists and tuples are both used to group multiple values together, with lists being linked collections that allow for dynamic sizing and tuples being fixed-size collections that provide fast access to elements. Maps are key-value stores that enable dynamic associations between data points, making them versatile for representing structured data. Structs are a special kind of map with a predefined set of keys, providing clarity and compile-time checks. Each of these data types has its specific use cases and performance characteristics, allowing developers to choose the right type for their data needs. By mastering Elixir's data types, you can write cleaner, more effective code that leverages the strengths of the language.
