javascript

This code is a JavaScript implementation for a canvas-based web application, primarily focusing on physics and user interaction. It creates a responsive canvas element where a rectangle can be controlled using keyboard inputs, simulating gravity and jump dynamics.
Key Features:

• Gravity Simulation: Variables control gravity strength and jump force.
• Linear Interpolation (lerp) Function: Smooths the movement transitions.
• Dynamic Canvas Resizing: Adjusts to window size changes.
• Rectangle Movement: Controlled by arrow keys and spacebar for jumping.
• Event Listeners: Handles key presses for interactive movement.
• Class-Based Rectangle Management: Simplifies creation and updating of canvas elements.

This script effectively merges basic physics principles with interactive elements for web-based games or animations.
