Objectives
- Master ES6+ fundamentals — let/const, arrow functions, destructuring, spread/rest, template literals, and ES modules.
- Understand asynchronous JavaScript — Promises, async/await, generators, and async iteration patterns in depth.
- Apply modern class features confidently — private fields, Proxy/Reflect, Symbols, and Map/Set in real scenarios.
- Practice with 600+ scenario-based questions covering ES2015–ES2023+ features, each with detailed explanations.
Pre Requisites
- Basic familiarity with JavaScript fundamentals (variables, functions, arrays, objects) is recommended.
- No prior experience with ES6+ syntax is required — every question includes a full explanation of why each answer is right or wrong.
- A willingness to learn through practice; this is a practice-test course, not a video tutorial.
FAQ
- Q. How long do I have access to the course materials?
- A. You can view and review the lecture materials indefinitely, like an on-demand channel.
- Q. Can I take my courses with me wherever I go?
- A. Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don't have an internet connection, some instructors also let their students download course lectures. That's up to the instructor though, so make sure you get on their good side!
