How to download a file from URI using Javascript

We create a temporary <a href="uri" target="_blank" download="filename" /> element using Javascript, append it to document.body and then trigger elemnt.click().

function downloadURI(uri, name) {
	const link = document.createElement("a");
	link.href = uri;
	link.download = name || uri.split('/').pop();
	document.body.appendChild(link);
	link.click();
	document.body.removeChild(link);
}
