Who needs javascript if you have dart? Who needs dart if you have go? Who needs go if you have erlang? Who needs erlang if you have c? Who needs c if you have assembly? Who needs assembly if you have binary code? Who needs binary code if you can just control electric signals by manually plugging and unplugging a cable to the wall?
Apparently all you need to build a good website is a power cord and some patience!
e.g. instead of
"hello\n" +
"world";
use
`hello
world`;
