Object

A collection of related data stored as key value pairs.

Detailed Explanation

An object is a collection of related data grouped together using key value pairs. While arrays store ordered lists, objects store named properties. A user object might have a name, email, and age property.

Objects are everywhere in JavaScript -- API responses (JSON), Component props, Database records, and configuration files are all objects. You access object properties using dot notation or destructuring. Objects can be exported and imported between files, stored in variables, and nested inside other objects or arrays.

Understanding objects is essential because nearly all real world data is structured as objects or arrays of objects.
