Sure, I can help you create a simple plane game using JavaScript. Here's an example implementation using HTML and JavaScript, which you can save as a single HTML file and run in a web browser:
This simple game includes a player-controlled jet that can be moved up and down using the up and down arrow keys. Pressing the spacebar will fire the player's gun, and the objective is to shoot down the enemy jets that approach from the right side.
Feel free to modify and enhance the game as per your requirements.
