Daily Term: Promises

Promises

Promises are a JavaScript feature for managing asynchronous operations, providing a cleaner alternative to callbacks. A Promise represents a value that may be available now, later, or never, with three states: pending, fulfilled, or rejected. For example, fetching data from an API returns a Promise, which you can handle with .then() for success or .catch() for errors. Promises improve code readability and error handling but can still lead to chaining complexity if overused.
