var arr = Array(10_000_000).fill(0);

Tests:

const n = arr.length;
const acc = new Array(n * 2);
for (let i = 0; i < n; i++){
  const x = arr[i];
  acc[i * 2] = x;
  acc[i * 2 + 1] = x * 2;
}

 
const n = arr.length;const acc = new Array(n * 2);for (let i = 0; i < n; i++){  const x = arr[i];  acc[i * 2] = x;  acc[i * 2 + 1] = x * 2;}
