A Donger is a set of unicode characters in a sequence that makes an emoticon. It’s a little, one-line text person, similar to ASCII art.
Here are some examples from the authoritative Donger source Donger List:

You get the gist.
If you’ve just now thought to yourself “I definitely need to put some of those in my web application,” today is your lucky day! You can now get an npm package that easily generates Dongers for all your Donger needs. Terminal messages! Alert boxes! One cool use would be as randomly generated profile pictures on forums or discussion sites. The sky is the limit! ୧༼ʘ̆ںʘ̆༽୨
