Most beginners learn JavaScript basics but get stuck when they try to build something real. They cannot connect code to a webpage. They have no idea how to fetch live data. This course closes that gap.

Here is what you will mainly cover: • DOM Manipulation & Events Choose elements using getElementById, querySelector, and querySelectorAll. Modify content with textContent and setAttribute. Handle click, input, & form events by using addEventListener and event delegation. • Asynchronous JavaScript Write callback functions. Chain Promises with resolve, reject, and then catch. Make use of async/await. Finally, handle parallel requests with Promise.all & errors with try/catch. • API Integration Make GET, POST, PUT, and DELETE requests implementing the Fetch API and XMLHttpRequest. Parse JSON, apply retry logic, and handle authentication headers. • ES6 Plus Features Apply ES6 Modules, destructuring, spread, rest, Symbols, Maps, Sets, optional chaining, nullish coalescing, and advanced array methods in case of real projects. Taught in Hindi and ideal for beginners and self-taught developers ready to build interactive UIs, async workflows, and API-connected applications.
