Shorthand string to number (JS)

I just discovered a neat little trick; you can convert strings to numbers using a unary plus operator as opposed to parseInt() or Number()

eg.

var x = '23';

console.log(parseInt(x));
console.log(Number(x));
console.log(+x);

only work with digit string, no other character allow.
parseInt() is safer.
