so beauty

The || c part is so good.

I would imagine there are some situation in which bitwise would be optimal... couldn't one then simply comment the code for the next developer whom may have to manage the code?

I wouldn't recommend using bitwise operators in production code they are really hard to understand and debug. I had hard time debugging production code that utilized bitwise operators.

great

~~: I learned something new today.
the while conditions, and the way u use res is very good but...
wew... took me a while to figure out what ur doing with c... true = 1, false = 0... useing that is brilliant.

Brilliant

this solution is realy cool!
My is much longer.

😭

that makes me feel weak

This is nuts... There really is very smart people out there. It's hard not getting my ego hurt after seeing solutions like this, I could not crack it on my own. Congratulations

Oh, it works :) I thought that transforming long string into array and operation on array will be too memory consuming and I did operation directly on string, but in almost the same way: while loop + removing last char from 'a' and 'b'. Although my solution is longer...

:( my solution always long :(______

This is like old school addition except you have to translate that into javascript. Life
