Keep in mind that this also works for hexadecimal.
console.log(+"0xF"); // 15 console.log(+"321"); // 321
And so does ~~
~~
console.log(~~"0xF"); // 15 console.log(~~"321"); // 321

it's the NOT bitwise operator. It changes the 1 by 0 and 0 by 1. In that example, he is doing it twice.
~ 5 => ~0101 => 1010 ~~5 => ~(~0101) => ~(1010) => 0101 => 5
