What is the use of the Confirm Function in JavaScript ?

The confirm function in JavaScript is used to display a modal dialog box with a message and two buttons: “OK” and “Cancel”. It is commonly used to obtain user confirmation for an action or decision in a web application.

Example: Here, the confirm function displays a dialog box with the message “Do you want to proceed with the action?” and “OK” and “Cancel” buttons. The user’s choice is then stored in the userConfirmation variable. If the user clicks “OK,” the variable will be true; if the user clicks “Cancel” or closes the dialog, the variable will be false.

Javascript

let userConfirmation = confirm(`Do you want to
proceed with the action?`);

if (userConfirmation) {
    console.log("User clicked OK.");
} else {
    console.log("User clicked Cancel or closed the dialog.");
}
