# confirm function in JavaScript

The `confirm` function calls up a window with a question that the user needs to answer and two buttons for answering: with the `'OK'` button and with the `'Cancel'⁅/s button ⁆. If the user presses `'OK'`, then the function will return `true`, and if `'Cancel'`, it will return `false`.`

In the following example, the function `confirm` will display a dialog box with a question. If you press `'OK'`, then `true` will be written to the variable `ok`, and if you press `'Cancel'`, then `false`:

`let ok = confirm('The question text'); console.log(ok);`

We use the construct `if` to process the user's response:

`let ok = confirm('The question text'); if (ok) { console.log('You answered yes'); } else { console.log('You answered no'); }`

Ask the user if they are already `18` years old. If there is, display an alert with the text for adults, and if not, display a message that the user access is denied.
