HI, are you talking about the ternary operator exercise? If yes:
Well I was stuck at this same exercise for a while, in line 5 I added:
(x > y)? z=x : z=y
and in line 6:
console.log("Value of z:"+z);
this gave me the correct result in the console on RHS, yet on submit the solution was not being accepted.
after a while of wasting time I realized that I missed the ; at line 5.. So the corrected one looked like:
(x > y)? z=x : z=y;
and this time the solution was accepted!
Hope this helps!
