Test name	Executions per second
array i/o	27.0 Ops/sec
typedArray i/o	26.5 Ops/sec

Script Preparation code:

var a = [...Array(100000)].map(_ => Math.random());
var ta = (new Float64Array(100000)).map(_ => Math.random());

Tests:

array i/o
for (let i = 0; i < 100000; ++i) a[i] = a[i] + 1;
typedArray i/o
for (let i = 0; i < 100000; ++i) ta[i] = ta[i] + 1;
