/əˈreɪ/ · Noun · Development
Definitions
A contiguous, indexed collection of elements of the same type stored in memory, providing O(1) random access by index and serving as the foundation for most higher-level collection types.
In plain English: An ordered list of items stored side by side in memory, where you can instantly jump to any item by its position number.
Example: "Arrays give you constant-time lookups, but inserting in the middle means shifting everything after it."
