Ternary vs Switch vs If (v6)

Revision 6 of this benchmark created by Richard Dillman on

Description

Testing which is faster, ternary, switch, if, if else if, or if else if else. (modified comparison operators to test for exact match ===)

Setup

var a = Math.floor(Math.random() * 4),
        t;

Teardown


    a = Math.floor(Math.random() * 4);

Test runner

Ready to run.

Ternary

Switch
switch (a) {
case 1:
  t = 1;
  break;
case 2:
  t = 2;

If
if (a === 1) t = 1;
