This repo is a popular collection of JavaScript questions with detailed, approachable explanations that help you understand why the language behaves the way it does. It covers tricky corners—hoisting, closures, coercion, event loop, prototypes, this binding, async/await, and more—through short prompts followed by illuminating answers. Explanations often include runnable snippets and step-through reasoning so you can replicate results locally. The content is curated to sharpen mental models rather than memorize trivia, making it valuable for interviews and day-to-day debugging alike. Because questions range from beginner to advanced, you can use it as a progressive study set or a quick refresher before assessments. It’s equally helpful for mentors: the questions can anchor study groups, workshops, or code-review discussions.
