Answer 1

//This returns true
var a = Boolean("A");
//true

while(a){

//This converts 'a'(true) to number 1
// here 'a' is 1

let my = a+10;

//This makes 'a' false so the loop stops

a = Boolean();

//This logs 11(because true + 10 is 11)

console.log(my);
}

VEDANG thanks!
I also assumed that the mathematical calculation converts "true" to "1", but decided to make sure. ☺
