Benchmark Run Result for: Do TypedArrays slow down when you add attributes to them?

Test name	Executions per second
without attributes	1115.5 Ops/sec
with attributes	1115.4 Ops/sec

Script Preparation code:

var array = new Float32Array(10000);
var array_with_attributes = new Float32Array(10000);
array_with_attributes.foo = 1;

Tests:

without attributes
for (var i = 0, li = array.length; i < li; i++) { array[i] = i; }
with attributes
for (var i = 0, li = array_with_attributes.length; i < li; i++) { array_with_attributes[i] = i; }
