Revision 8 of this benchmark created by Josh 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.

Switch
