Set Splits Strings

Examples of JavaScript's Set usually include an array as the argument:

const arraySet = new Set([1, 2, 3, 4, 5]);

However, the Set constructor also accepts a string, splitting it into a set for you:

const text = 'India';

const stringSet = new Set(text);  // Set ['I', 'n', 'd', 'i', 'a']

Enjoy those extra keystrokes!
