What is the use of the Prompt Function in JavaScript ?

The prompt function in JavaScript is used to interact with the user by displaying a dialog box that allows the user to type input text. It is often used to gather user input simply.

Example: Here, the prompt function displays a dialog box with the message “Please enter your name:” and an input field. The user can enter text, and the entered value is stored in the userInput variable. The script then prints a greeting using the entered name.

Javascript

let userInput = prompt("Please enter your name:");

console.log("Hello, " + userInput + "!");
