Short circuiting is poor for readability in my view because not only do you have to parse the syntax but you need to mentally walk through each case to understand what’s going on.

Traditional if/else conditionals express clarity by embedding the decision for myVar and visually show how it would be assigned in various cases.

As @hotBacteria said:

  if(cond1){
   myVar = 1;
  } else if(cond2 && cond3){
   myVar = 10;
  } else if(cond2 && !cond3){
   myVar = 100;
  } else {
   myVar = 4;
  }

  // Now return myVar
  return myVar;

I’ll take this syntax over short circuiting any day.
