// Version A. Allegedly Faster var a = 1, b = 2, c = 3; // Version B. Allegedly Slower var a = 1; var b = 2; var c = 3;
However, when googling to confirm this I only find rants about how some consider the second example to be simpler from a maintenance point of view. And some disagree. This JSPerf test sais there is no difference.
So my question: From a performance perspective, is there any reason version A or B would be better?
