155 JavaScript questions that look easy and aren't: choose an answer, then learn why

Can you still read code? is a browser-based quiz of 155 JavaScript questions. Each question shows a few lines of code with one correct answer and a short explanation of the result. The site is pitched at developers who rely on coding agents and want to keep their own code-reading skills sharp. It describes each question as a small workout for your memory and your mental model of the language. The questions and explanations come from Lydia Hallie's javascript-questions, used under the MIT licence. The app is open source, and visitors can contribute new questions.
