Most of the terminal emulators auto-detect when a URL appears onscreen and allow to conveniently open them (e.g. via Ctrl+click or Cmd+click, or the right click menu).
It was, however, not possible until now for arbitrary text to point to URLs, just as on webpages.
Inspired by the Perl6 pointy block short syntax (https://docs.perl6.org/type/Whatever) I like functional programming in JS. And it will be great to have even shorter syntax for lambdas (than arrow functions).
The compiler should detect special syntax and convert it to arrow functions.
Motivation: With shorter syntax it is clearer what is the intent of the code. Moreover, we do not write variable names twice. It is like when you contruct on object obj = {name: name, email: email} you use shorter syntax obj = {name, email}. Here it similar appoach.
Here are some examples. For every example bothe notation are the same.

I work at Grammarly. We like React and happily use it in our applications. However, sometimes something goes wrong and bugs creep into the code. Here comes testing. It helps make us confident about the quality of our code.

@kangax created a new interesting quiz, this time devoted to ES6 (aka ES2015). I found this quiz very interesting and quite hard (made myself 3 mistakes on first pass).
Here we go with the explanations:
(function(x, f = () => x) {
| sh_stats () { | |
| fc -l 1 | awk '{CMD[$2]++;count++;}END { for (a in CMD)print CMD[a] " " CMD[a]/count*100 "% " a;}' | grep -v "./" | column -c3 -s " " -t | sort -nr | nl | head -n20 | |

I say "animated gif" but in reality I think it's irresponsible to be serving "real" GIF files to people now. You should be serving gfy's, gifv's, webm, mp4s, whatever. They're a fraction of the filesize making it easier for you to deliver high fidelity, full color animation very quickly, especially on bad mobile connections. (But I suppose if you're just doing this for small audiences (like bug reporting), then LICEcap is a good solution).
