I am most excited about template strings, simply because they let you write multiline strings.
e.g. instead of
"hello\n" +
"world";

`hello
world`;
e.g. instead of
"hello\n" +
"world";
use
`hello
world`;
One nice thing about the template strings in TypeScript is you can use those and still compile to ES3/ES5 for today's browsers.
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!
