About this app
This app teaches JavaScript through lessons, quizzes, and an in-app code editor. It covers JavaScript from fundamentals to advanced topics, including the event loop and asynchronous programming.
Lessons
Content is organized as Subject โบ Topic โบ Subtopic. Each subtopic includes theory, a worked example, and a summary. Topics include variables and hoisting, functions and closures, lexical scope, the prototype chain, objects and destructuring, iterators and generators, and ES6+ syntax such as arrow functions, classes, modules, and BigInt. Lessons include completion markers, search, and bookmarks.
Code editor
An in-app editor runs JavaScript and shows the output. You can use array methods, Promises, fetch, async/await, and DOM manipulation without installing anything. Coding problems include hidden test cases and reference solutions. The editor also runs Python, Java, C++, Go, Rust, Kotlin, and Swift.
AI tutor
You can ask questions in plain language and receive answers based on the current lesson. You can submit a photo of code or a diagram, practice mock interview questions, and ask the AI to explain code output.
Quizzes and mock tests
Multiple-choice questions are graded Easy to Hard, and each answer includes an explanation. Timed tests combine theory and coding questions and report topics that need review, such as the event loop, closures, and async patterns. Past attempts can be reviewed and retaken.
Progress tracking
The app records scores, study time, and completed topics. It includes a 7-day study plan, a daily check-in quiz, a revision card, and global and per-subject leaderboards.
Languages and offline use
The app works offline for downloaded content and supports light and dark themes. The interface is available in English, Hindi, Kannada, Tamil, and Telugu; JavaScript code and technical terms are kept unchanged during translation. A technology news feed is included.
