Asynchronous JavaScript

Welcome to Week 6: Asynchronous JavaScript

Welcome to Week 6, where we dive into the world of Asynchronous JavaScript. This topic is crucial for understanding how JavaScript interacts with activities that take time to complete, such as fetching data from a server, writing to a database, or performing complex computations.

We'll begin with an introduction to asynchronous programming and the difference between synchronous and asynchronous execution models. From there, we'll dive into callbacks, the earliest method for handling asynchronous operations in JavaScript.

Next, we'll explore Promises, a more modern technique for managing asynchronous operations, followed by the even more recent async/await syntax, which makes our asynchronous code look and behave like synchronous code.

We'll also explore the process of calling APIs, an essential part of almost every modern web application, and learn about Browser APIs, the web-based APIs provided by the browser environment.

The week will culminate with a project, where you'll apply your understanding of asynchronous programming in a real-world scenario.

Learning Objectives

By the end of this week, you will be able to:

  • Understand the concept of asynchronous programming and its significance in JavaScript
  • Distinguish between synchronous and asynchronous execution in JavaScript
  • Use callbacks to handle asynchronous operations
  • Understand what Promises are and use them to manage asynchronous tasks
  • Implement the async/await syntax to write asynchronous code in a more readable manner
  • Call APIs to fetch data from a server and handle the response
  • Understand what Browser APIs are and how to use them
