This course now features Coursera Coach! A smarter way to learn with interactive, real-time conversations that help you test your knowledge, challenge assumptions, and deepen your understanding as you progress through the course. JavaScript wasn't initially designed for asynchronous operations, but with some adjustments, you can effectively manage asynchronous code to ensure data is used only after it's fully fetched. In this course, you'll master every aspect of asynchronous JavaScript through easy-to-understand examples and detailed explanations. You'll explore event loops, JavaScript's behind-the-scenes workings, asynchronous code execution, callbacks and their limitations, the advent of promises, and how Async Await beautifies promises. You'll apply these concepts in three real-world mini-projects, including handling multiple promises and errors using Async Await. By the end, you'll have a thorough understanding of asynchronous JavaScript. Designed for JavaScript developers, web developers, programmers, and front-end developers familiar with frameworks like Angular, React, Vue, or Svelte, this course will elevate your asynchronous programming skills and enhance your resume. Some knowledge of JavaScript will be an added advantage to get through the course.
