How to change placeholder text with JavaScript?

You can change the placeholder text of an HTML element in JavaScript by using the placeholder property. To set the placeholder text, you can assign a string value to the placeholder property.

Here’s an example:

const input = document.querySelector('input');

input.placeholder = 'Enter some text';

In this example, we select an input element and change its placeholder property to a string value 'Enter some text'. The new placeholder text will be displayed in the input element until a user enters some text or the placeholder property is changed again.
