Описание тега fetch-api
The Fetch API is an improved replacement for XHR, for making asynchronous HTTP requests while better managing redirects and interaction with CORS and Service Workers.
The core of the Fetch API is a JavaScript method simply called fetch, for making asynchronous HTTP requests and for handling the responses from those requests.
