Ruby Data Types and Data Structures
Ruby has several basic data types including integers, floats, strings, symbols, arrays, hashes, and sets. Integers can be Fixnums for smaller whole numbers or Bignums for larger numbers. Arrays can hold a group of values of different types and are defined with square brackets. Hashes use a key-value pair structure with keys that can be strings or symbols. Sets are an unordered collection of unique values that can be created in Ruby.
