Float32Array vs Array (v6)

Revision 6 of this benchmark created by eweitnauer on

Description

Creation, initialization, reading and writing of a 10000 element array vs. float32array.

Setup

var f32_10000 = new Float32Array(10000);
    var arr_10000 = new Array(10000);
    var f32_1000 = new Float32Array(1000);
    var arr_1000 = new Array(1000);
