Script Preparation code:

var size = 1024;

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

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

Tests:

const arr = new Float64Array(size);
for(let i = 0; i < size; i++) {
  arr[i] = initialArray[i]/2;
}

 
const arr = new Float64Array(size);for(let i = 0; i < size; i++) {  arr[i] = initialArray[i]/2;}
