In JavaScript, objects are one of the most fundamental and versatile data types. They are collections of key-value pairs, where the keys (also called properties) are strings or symbols, and the values can be of any data type, including other objects, functions, or arrays.
Prototypal Inheritance: Objects can inherit properties and methods from other objects using prototypes.
Dynamic Structure: Objects can have properties added or removed dynamically.
Flexibility: They can store mixed data types and methods (functions that belong to the object).
