var openA;
var dayA;
var weekendA = 2;

  1. no problem with this one:
    openA = ( dayA == weekendA) ? 12 : 9;

  2. i’d like to know the correct way to do this one:
    openA = ( dayA == weekendA) ? print(“hallo”) : print(“bye”);

thanks for your help and time.

You can’t use the ternary operator as a function call without assignation. print() doesn’t returns void.

Use If/Else, or maybe try to explain more of what it is you want to accomplish with that statement (how would openA = print(“hallo”) work for example).

As well, since you are performing a function call, the ternary operator isn’t going to save you a branch anyway, so it’s not an improvement performance-wise over if/else.

print((dayA == weekendA) ? "hallo" : "bye");

Unless you also want to assign hallo to openA:

openA = (dayA == weekendA) ? "hallo" : "bye";
print(openA);

thanks alot. i found very usefull both of them:

print((dayA == weekendA) ? “hallo” : “bye”);

openA = (dayA == weekendA) ? “hallo” : “bye”;
print(openA);

i solved my problem in these 2 ways:

openA = ( dayA == weekendA ) ? ( week++ ) : ( week-- ) ;
print ( openA );
print ( week );

var openA = 2;
var dayA = 5;
var weekendA = 5;
var week = 10;

openA = ( dayA == weekendA) ? (week + dayA) + 2 : (week - dayA) - 2;

print (openA);

sorry i did not explain the problem in the first post;
i just wanted to know if it is possible to insert inputs more complex than just numbers in this

variable = condition ? value if true : value if false;

just in case, if i need to use brackets is it correct to think like this?

variable = condition ? value if true : (((week+1)/2)*3);
