Splicing a single value (v48)

Revision 48 of this benchmark created on

Setup

var arr = new Array();
    for (var i = 0; i < 10000; i++) {
     arr.push({ b: i });
    };
    for (var i = 65000; i < 70000; i++) {
     arr[i] = { h: i };
    };
    var half = Math.floor(arr.length / 2);
      
    function randomInt(max) {
     return Math.floor(Math.random() * (max + 1));
    };
