Make getUrlObject private?

[Ryuno-Ki]

Looking at

tweetback/src/twitter.js

Lines 115 to 151 in d03e289

	getUrlObject(url) {
	let expandedUrl = url.expanded_url ?? url.url;
	let displayUrl = expandedUrl;
	let className = "tweet-url";
	let targetUrl = expandedUrl;
	// Links to my tweets
	if(displayUrl.startsWith(`https://twitter.com/${metadata.username}/status/`)) {
	targetUrl = `/${expandedUrl.substr(`https://twitter.com/${metadata.username}/status/`.length)}`;
	}
	// Links to other tweets
	if(displayUrl.startsWith("https://twitter.com") && displayUrl.indexOf("/status/") > -1) {
	displayUrl = displayUrl.substring("https://twitter.com/".length);
	displayUrl = displayUrl.replace("/status/", "/");
	displayUrl = `@${displayUrl}`;
	// displayUrl = displayUrl.replace(/(\d+)/, function(match) {
	// return "" + (match.length > 6 ? "…" : "") + match.substr(-6);
	// });
	className = "tweet-username";
	} else {
	if(displayUrl.startsWith("http://")) {
	displayUrl = displayUrl.substring("http://".length);
	}
	if(displayUrl.startsWith("https://")) {
	displayUrl = displayUrl.substring("https://".length);
	}
	if(displayUrl.startsWith("www.")) {
	displayUrl = displayUrl.substring("www.".length);
	}
	}
	return {
	displayUrl,
	className,
	targetUrl,
	}
	}

it appears to be used only within this class. Therefore I suggest to declare it as a private method (by prefixing it with an underscore or using private class feature).
