EPISODE 7 – Promises

Promises are one of the most important concepts in JavaScript for handling asynchronous operations. Misunderstanding them has caused countless bugs, especially in real-world applications.

In this video, you’ll learn:

• A Promise represents a value that is not available yet but will be resolved in the future.
• Every Promise has three states:
  

  1. Pending – the operation is still in progress

  2. Fulfilled – the operation completed successfully

  3. Rejected – the operation failed due to an error

• The .then() method is used to handle successful results.
• The .catch() method is used to handle errors and failures.
• Promises help avoid callback hell by providing a cleaner and more readable structure for async code.
• Using Promises makes asynchronous JavaScript easier to debug, maintain, and scale.

Understanding Promises is essential for working with APIs, handling network requests, and building modern JavaScript applications.
