interface and the game's functionalities, we will be needing JavaScript. We will need the following JavaScript files in the scripts folder: app.main.jsapp.display_functions.jsapp.init.jsapp.key_handler.jsapp.movement_functions.jsapp.constants.js The app.main.js file Our app.main.js file should contain the following function that will deal with the app.key_handler.js file and your computer's keyboard. It will also call the app.init.js file for the initialization of our variables. Note Here we

Variables We already know that the computer world has nothing but data. There are different types of data (we call them data types), as follows: Your name is a kind of dataYour age is dataYour grade is also data Yet, they all are different. What is the difference between them? Your name only contains a group of characters or, as some people also
