Script Preparation code:

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

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

Tests:

for (let i = 0; i < 100000; ++i)
  a[i] = a[i] + 1;

 
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;
for (let i = 0; i < 100000; ++i)
ta[i] = ta[i] + 1;
