Re: Ternary operator optimization tip

While it is slower due to the use of temp vars, in my experience unless you have a few hundred operations involving ternary operator you cannot even see the difference. Even then there are typically way more important areas of code that need to be optimized. The only time you can really tell its slower is in synthetic benchmarks. Few hundred operations involving ternary operator is nothing unusual ;)
