In JavaScript, a Promise represents a value that may be available now, or in the future, or never. A Promise has three possible states:

  1. Pending: The initial state of a Promise. The operation is still ongoing, and the eventual outcome is not yet determined.
  1. Fulfilled: This state indicates that the Promise has completed successfully, and a resulting value is available.

  2. Rejected: This state indicates that the Promise has completed but with an error or failure, meaning the anticipated value is unavailable.

The term "Failed" is not used in the context of Promise states. While it may be a common interpretation of an error occurrence, in JavaScript, a Promise is either fulfilled or rejected when the asynchronous operation completes. By clearly defining these specific states (Pending, Fulfilled, and Rejected), JavaScript provides a structured way to handle asynchronous operations, making it easier for developers to manage success and error scenarios effectively.
