Promises are a programming concept used to handle asynchronous operations. They represent the success or failure of an asynchronous operation and allow for writing more readable and maintainable code.
In JavaScript, for instance, promises enable functions to execute asynchronous tasks and then either return a value (success) or an error. A Promise object can be in one of three states: pending, fulfilled, or rejected.
They are often used to create code blocks that wait for the result of an asynchronous operation, allowing a series of operations to be executed in a specific order or making asynchronous calls in parallel while keeping the code readable and well-organized.
With ES6 and later versions of JavaScript, promises have become a fundamental part of the language, often used in conjunction with functions like fetch for network requests or other asynchronous operations.
