Understanding Promises and the Pending State

A promise in JavaScript represents an operation that hasn't completed yet but is expected to do so in the future. Promises can be in one of three states:

Pending: The initial state, neither fulfilled nor rejected.

Fulfilled: The operation completed successfully.

Rejected: The operation failed.

Can You Turn Off Promise { ＜pending＞ }?

Directly turning off the Promise { ＜pending＞ } message isn't possible since it's an inherent part of how promises are represented in JavaScript. However, you can manage how and when you log promise-related information to avoid confusion.

Handling Promises Effectively

To avoid seeing the Promise { ＜pending＞ } message, ensure you're handling the promise resolution before logging. Here are some methods to handle this:

Using .then():
Chain a .then() method to the promise to log the result after it has resolved.

Using async/await:
With async/await, you can write asynchronous code that looks synchronous, making it easier to handle and log resolved promises.

Handling Errors with .catch():
Always include error handling to manage rejected promises and avoid unhandled promise rejections.
