Not clear on how this outputs 110, please explain if you can..

Question

function bin (number) {
var res = "";

while (num > 0) {
res = num % 2 + res;
num = Math.floor (num/2);
}
return res;
}

document.write (bin(6));

Answer 1

you are extracting the binary number of 6 which is 110
i made a code close to this

Answer 2

explanation:
6 %2 is 0
6/2=3
3%2=1
you are adding it to the left of the previous value so now res=10
3/2=1
1%2=1
res=110

Answer 3

Thank you @Dominique!

But why are we adding to the left of previous value instead of how it's done normally?

Answer 4

that is right way to convert into binary. it is also the right way to convert any base number (base 2 for binary, 16 for hexadecimal.)
base 10 is the normal decimal numbers we usually use
