Description: Parameter passing is the method of providing input to functions or methods in programming. This concept is fundamental in most programming languages, including JavaScript and, by extension, many frameworks. When defining a function, parameters act as variables that will receive values when the function is invoked. This allows functions to be more flexible and reusable, as they can operate on different data without the need to rewrite the code. In the context of web development, parameter passing is used to handle HTTP requests, allowing developers to pass data from the client to the server efficiently. Parameters can be of different types, including route parameters, query parameters, and body parameters, each with its own way of being accessed and used within the application. This ability to pass information in a structured manner is essential for building dynamic web applications and effectively responding to user interactions.
