Khan Academy — Answer Revealer
A popular YouTube tutorial suggests right-clicking a problem, selecting "Inspect," and finding the answer hidden in a data-value tag. This used to work on very old, static problems. However, Khan Academy now uses dynamic React.js rendering. Answers are often encrypted, stored server-side, or only revealed after an API call to their backend. You might see the text of the question, but rarely the correct multiple-choice letter.
Khan Academy is a sophisticated web application. The "answer" isn't hidden in your browser's code waiting to be read. When you submit an answer, the browser sends a request to Khan Academy’s servers. The server checks the answer. No local script can bypass that server-side logic. Most "revealers" simply try to scrape the DOM (the visual structure of the page) for hints—which rarely works.
