Data Structures

Ra supports basic data structures like arrays and dictionaries.

Arrays​

Arrays are ordered collections of elements:

let arr = [1, 2, 3, 4];
puts(arr[0]);  # Access the first element

push(arr, 5);  # Add an element
puts(arr);  # Print the array
puts(len(arr));  # Print the length of the array

Dictionaries​

Dictionaries store key-value pairs:

let person = {"name": "Alice", "age": 30};
puts(person["name"]);  # Access value by key
