🚀 Feature: Also export a byEmoji object, in addition to byTitle

Overview

Right now, emoji-platform-data exports a byTitle object that maps emoji titles to their accumulated data:

import { byTitle } from "emoji-platform-data";

console.log(byTitle["Sparkling Heart"]);
/*
{
	emoji: "💖",
	emojipedia: { "currentCldrName": "Sparkling Heart", ... },
	fluemoji: { "cldr": "sparkling heart", ... },
	gemoji: { "description": "sparkling heart", ... },
	twemoji: { "description": "Sparkling heart", ... },
	...
}
*/

...but, not everyone will want to refer to emojis by the approximate Apple name / CLDR name. Many folks will want to refer to them by their emoji. Roughly:

// Proposing:
import { byEmoji } from "emoji-platform-data";

console.log(byEmoji["💖"]);

Additional Info

It's a pity you can't do export get byEmoji() { ... } in ESM. Looping over all existing emojis might take some time... In my playing with this locally, it's 5-6ms. Not the worst penalty in the world. I think it's fine: the use cases for emoji-platform-data are really more around data analysis / emoji comparisons, not performance-critical real-world consumer applications.
