Switch-case vs. if/else (v13)

Revision 13 of this benchmark created by Eddie Prislac on

Setup

var v = 0 | Math.random() * 9 + 1; // 1 to 9
  var sum;
  const sumObj = {
   1: "A",
   2: "B",
   3: "C",
   4: "D",
   5: "E",
   6: "F",
   7: "G",
   8: "H",
   9: "I"
  };
  
  const sumArr = ['A','B','C','D','E','F','I','G','H','I']
