Mungkin saya luruskan dulu pengertian CORS nya. Sebenernya "CORS error" di browser terjadi karena browser Fetch API tunduk sama same-origin policy. Jadi defaultnya, JavaScript yang di serve di situs https://domain-a.com tidak dibolehkan browser melakukan http request ke https://domain-b.com/data.json.

Justru CORS (Cross-Origin-Resource-Sharing) itu mekanisme yang membolehkan kode JavaScript yang di browser yang di serve di https://domain-a.com untuk melakukan http request ke domain lain contohnya https://domain-b.com/data.json.

Implementasinya seperti apa?

Melalui http header Access-Control-Allow-Origin dari server. Kalau misalnya http header itu valuenya *, berarti CORS enabled, jadi javascript dari website apapun dibolehkan browser mengakses resources dari server tersebut.

Here's the list of my React sandboxes. The purpose is to have a reproducible exploration into the React ecosystem.
It is linked to the repo and sandbox:

React 17 without automatic batching. [repo][sandbox]
React 18 with automatic batching. [repo][sandbox]
Page scrolling into an element by id. [repo][sandbox]
Internationalization (I18N) with aws-amplify. [repo][sandbox]
Styling MUI DatePicker. [repo][[sandbox](https://codesandbox.io/s/github/artidata/styling-m

Here's the list of things that compile or transpile to JavaScript. The list only includes those who have website compiler. It is ordered alphabetically and linked to the playground:

Sites that use React:

	function computeClosestToZero(arr: number[]) {
	return arr.length > 0
	? arr.sort((a, b) => {
	let absDiff = Math.abs(a) - Math.abs(b);
	return absDiff === 0 ? b - a : absDiff;
	})[0]
	: 0;
	}
