"This video demonstrates coding in TypeScript within an infinite, dark-themed canvas environment. Three code windows showcase different TypeScript features: one defines a "Person" interface and logs an instance, demonstrating type checking and code completion; another illustrates DOM interaction and browser API access using document.getElementById and window.navigator.canShare along with type hints; and the last one highlights npm support by importing and using the "validator" (for email validation) and "redash" (for string transformation) libraries. The user interacts with the code by typing, deleting, and utilizing autocompletion suggestions, highlighting the dynamic nature of the interface, and drags the code windows across the scrollable canvas. A control panel in the top right corner offers customization options."
