Add New Line in Alert in JavaScript

window.alert() tells the browser to display a dialog with an optional message and wait for the user to close the dialog.

Under certain conditions, such as when the user switches between tabs, the browser may not display a dialog box or wait for the user to close the dialog box.

Syntax:

window.alert(message)

The alert method takes a character string you want to display in the alarm dialog or an object converted to a character string and displayed.

Dialogs are modal windows that prevent the user from accessing the rest of the program interface until the dialog is closed. For this reason, you shouldn’t abuse any function that creates a dialog (or modal window).

Let’s look at the example below.

alert('Hello World!\nWelcome to my blog post.');

In the above example, we have given two messages as an input argument to the alert function. Both messages are separated using \n, which means that the first message is displayed in the first row/line and another in the second row/line.

Try to run the above code in any browser that supports JavaScript, and it will show you the below result.
