Introduction

JavaScript is a synchronous language and React, being a JavaScript framework, is synchronous too. Being synchronous means only one line of code can be executed at a time and the next line of code cannot start until the current code has finished executing. This can cause an issue when we make network requests. When we make network requests in a synchronous fashion the code is executed sequentially from top to bottom. This means when one network request is executed, the remaining code has to wait until that network request is completed, which can dramatically reduce the user experience. The solution for that is to make asynchronous callbacks for network requests where the operations run in parallel. The Promise API provides a simpler way to manage asynchronous operations compared to the traditional asynchronous callbacks. The Promise API can also be easily integrated with React, which helps us to create asynchronous operations easily when making network requests in React...
