// HACK: String Important Interview Question?

// INFO: 1) What is the output of 10+20+"30" in JavaScript?
// => 3030 because 10+20 will be 30. If there is numeric value before
//    and after +, it treats as binary + (arithmetic operator).

// INFO:2) What is the output of "10"+20+30 in JavaScript?
// => 102030 because after a string all the + will be treated as
//    string concatenation operator (not binary +).
