Salesforce JavaScript Developer Practice Exam

The main benefit of using JavaScript modules lies in their ability to help organize code and encapsulate functionality. This modular approach allows developers to break their code into smaller, reusable components, each with its own scope.

By encapsulating functions, variables, and objects within a module, developers can prevent naming collisions and keep the global scope clean. This not only makes the code easier to understand and maintain over time but also promotes better collaboration among multiple developers by clearly defining the responsibilities and interfaces of each module.

Additionally, the organization of code into modules enhances readability and can simplify debugging and testing, as developers can focus on smaller, self-contained parts of the codebase. The modular structure also facilitates the reuse of components across different parts of an application or even across different projects, leading to improved efficiency and reduced redundancy.

Overall, using JavaScript modules is a best practice in modern development that leverages encapsulation to create more manageable and organized codebases.
