This should be the industry standard for uglifying js. I would love to inspect source of websites and find out that everything is an emoji.
Heh, this is quite funny. By quick reading, it seems to just encode the input JavaScript source bytes into emoji. A further development idea would be to parse the input file with one of the JavaScript JavaScript parsers, encode only select keywords, operators and number / string constants in emoji and leave the rest as as-is.
One could select clever emoji for the keywords (eg. if=pondering face, while=ferris wheel etc.) to produce a kind of shortened visual JavaScript emoji syntax.
fork it!
I love that the question of 'WHY?!' is asked and answered on their Github project page.
I work on an emoji-related project and always joke about the whole stack being emoji. Now, i can be soooo serious about it.
