Answer 1

while(3)
//b=2
a=3

while(2)
//b=1
a=4

while(1)
//b=0
a=5

Answer 2

Heidi Eigner

while loop will work until b becomes 0 and at the same time a will be increase by 1 so here b will be decrement by 1 and a will be increment by 1 so when b becomes 0, a becomes 5.

Answer 3

You may find it helpful to output a and b on each iteration to see what's going on

while(b--) {++a; console.log(a + ", " + b);};

Answer 4

This is perfect. Thanks
