This packages exposes all the possible emojis available in a slack chat.
One out of many possibilities is that you are writing a webhook feature which integrates with slack and you would like to use emojis,
you would have to use a magic string in your code(e.g 💥 <==> :boom: <==> slackEmojis.BOOM).
slack-emojis is here for the rescue!
const slackEmojis = require('slack-emojis');
console.log(slackEmojis.RELAXED); // outputs :relaxed:
