Destructuring: string

Destructuring also works on strings

destructure every character, just as if the string was an array

let a, b, c = 'abc'; assert.deepEqual([a, b, c], ['a', 'b', 'c']);

missing characters are undefined

const [a, c] = 'ab'; assert.equal(c, void 0);

unicode character work too

const [space, coffee] = 'a ☕'; assert.equal(coffee, '\u{2615}');

Required Knowledge
