How Can I Manually Trigger an 'onchange' Event in JavaScript?

Triggering 'Onchange' Events Manually

In the world of web development, 'onchange' events play a crucial role in responding to element value alterations. However, some scenarios arise where these events may not trigger automatically. For example, setting a date-time text field's value through a calendar widget.

To address this, we need a way to manually initiate an 'onchange' event, ensuring that it checks for value differences in the text field.

element.dispatchEvent(event);
