In plain language
In JSON, an object is the part in curly braces, where each field name points to a value.
Example
{"name": "Ada", "email": "ada@example.com", "company": "Acme"} is an object describing one contact.

Common misconception
An object is not a list; an array holds many items in order, while an object holds named fields for one item.
Implementation guidance
Reference fields by their key names, handle missing or null keys, keep nested objects shallow where possible, and validate structure with a schema.
