How do you echo a 4-digit Unicode character in Bash?
...
In UTF-8 it's actually 6 digits (or 3 bytes).

What does curly brackets in the `var { … } = …` statements do?
...es code much more succinct.
For example:
var ascii = {
a: 97,
b: 98,
c: 99
};

The above code is equivalent to:
var ascii = {
a: 97,
b: 98,
c: 99
};
var a = ascii.a;
var b = ascii.b;
var c = ascii.c;
Similarly for arrays:
var ascii = [97, 98, 9...
