There is a (long lost?) theory in web development and information theory called graceful degradation: “the practice of building your web functionality so that it provides a certain level of user experience in more modern browsers, but it will also degrade gracefully to a lower level of user in experience in older browsers. This lower level is not as nice to use for your site visitors, but it does still provide them with the basic functionality that they came to your site to use; things do not break for them.”
For example, turn off JavaScript in your browser and visit https://99percentinvisible.org/ or https://www.apple.com/ . The link for the ASCII ant colony, on the other hand, does nothing because it’s just a JavaScript generator.
