JavaScript, one of the most versatile and widely used programming languages for web development, offers several built-in functions that allow developers to interact with users effectively. Among these functions, alert, prompt, and confirm stand out as essential tools for creating dynamic and user-friendly web experiences.

Alert: Notifying Users It is used to display a simple pop-up dialog box with a message and an "OK" button. This function serves as a quick and direct way to communicate with users, providing notifications, warnings, or information.

Confirm: User Confirmation The confirm function, as its name implies, is used to gather user confirmation for an action. It presents a dialog box with two buttons: "OK" and "Cancel."

Prompt: User Input The prompt function allows developers to collect user input through a dialog box. It presents a message to the user, an input field for text entry, and "OK" and "Cancel" buttons.
