Script Preparation code:

var size = 1024;

var initialArray = [];
for(let i = 0; i < size; i++) {
  initialArray.push(Math.random());
}

Tests:

typed array
const arr = new Float64Array(size); for(let i = 0; i < size; i++) { arr[i] = initialArray[i]/2; }
not typed array
const arr = []; for(let i = 0; i < size; i++) { arr.push(initialArray[i]/2); }
