What is the purpose of using the prompt function in JavaScript?

The prompt function in JavaScript is specifically designed to collect user input. When invoked, it opens a dialog box that presents a message to the user, along with an input field where they can type in their response. This input is then captured and returned as a string. The primary purpose of prompt is to interact with the user and obtain data from them while the script is running.

Collecting user input is essential in many applications since it enables personalization and dynamic responses based on user actions or preferences. Understanding this function is key for developers looking to create interactive web applications where user feedback or data is essential for the application's functionality.
