Dynamic Element Content Changer with Keyboard Event

This project includes a JavaScript function (changeInnerHtmlById) that allows you to dynamically change the content of an HTML element using its selector. Additionally, there is an event listener attached to the keydown event that demonstrates the usage of this function by updating the content of several elements with information about the key pressed.

Project Overview

The primary goal of this project is to showcase a simple JavaScript function for dynamically updating HTML elements based on their selectors. The project also includes an event listener that captures the keydown event, providing real-time updates about the key pressed by the user.
