What is the primary purpose of JavaScript Promises?

The primary purpose of JavaScript Promises is to manage asynchronous operations and enable chaining. Promises are a powerful way to handle operations that take time to complete, such as API calls or file reading, without blocking the execution of other code.

When a Promise is created, it represents a value that may be available now, or in the future, or never. This ability to represent pending operations allows developers to write cleaner and more understandable code compared to using traditional callbacks.

Furthermore, Promises provide methods such as .then() and .catch() that facilitate chaining multiple asynchronous operations. This means you can set up a sequence of actions where the output of one operation can be used as the input for the next one, improving code readability and maintainability.

By using Promises, developers can manage complex flows of asynchronous data and error handling in a more structured way, making it easier to work with multiple operations that depend on one another.
