What’s This Course About?

Course overview

JavaScript promises play an important role in handling asynchronous operations, making the code more readable, and providing a better control flow of code execution. We will cover different aspects of JavaScript promises as we move ahead. Promise APIs and examples will be discussed in detail to help us learn new syntax and concepts.

• The “Basics of Promises” chapter will introduce you to the concepts of promises, how they work, and different ways to create and use them.

• The “Chaining Promises” chapter will detail the various ways to chain multiple promises to make composing asynchronous operations easier.

• In “Working with Multiple Promises,” we'll use the built-in JavaScript methods designed to monitor and respond to multiple promises executing in parallel.

• The “Async Functions and Await Expressions” chapter will introduce you to these JavaScript functions that are often used with promises.

• The last chapter, “Unhandled Rejection Tracking,” is about tracking promises when they are rejected without a rejection handler.
