JavaScript objects store, manipulate, and send data in a collection of name-value pairs.
Objects in JavaScript can be created using curly braces, constructors, Object.create() method, functions as blueprints, or classes.
Object.create() method allows creating objects from an existing blueprint to inherit properties and methods without constructors.
JavaScript offers various methods like object literals, new Object(), Object.create(), constructor functions, and classes to create objects based on different requirements.
