Salesforce JavaScript Developer Practice Exam

A JavaScript object is defined as a collection of properties, where each property consists of a key and a value. This structure allows for the organization of data in a way that is easily accessible and manageable. In JavaScript, objects can represent real-world entities and complex data structures, making them fundamental to the language. Each property can be of any data type, including other objects or functions, thereby enhancing their versatility.

This characteristic is central to object-oriented programming within JavaScript, as it enables developers to create intricate data models that are both modular and reusable. Understanding how to create and manipulate objects is vital for effective programming in JavaScript and is foundational to working with frameworks and libraries that build on these concepts.
