for loop research (v23)

Revision 23 of this benchmark created on

Description

Varius for-loop variants: * with length caching * with various counter increment (++i, i++) * while alternative

Setup

var arr = [];
    
    for (var i = 0; i < 1000; i++) {
      arr.push('arr-value-' + i);
    }
    
    function worker() {
      return (1 + 1);
    }

Test runner

Ready to run.
