FYI, the question and the result you ask for aren't the same thing. It looks like what you want is to make an array of arrays from two arrays, in which the two arrays are mapped on the overall index o each other... — Austin T French

You can use array.map to combine the array values at the same index.

const arr1 = [
  1589135400000,
  1589221800000,
  1589308200000,
  1589394600000,
  1589481000000,
  1589567400000,
  1589653800000,
  1589740200000,
  1589826600000,
  1591122600000,
];

const arr2 = [
  90.05,
  98.0225,
  99.8231,
  99.3969,
  73.45,
  68.356,
  55.123,
  100,
  68.75,
  98.02430,
];

const combined = arr1.map((n, i) => [n, arr2[i]]);

console.log(combined);

Just loop over the first and find the same index in the second

arr1 = [1589135400000, 1589221800000, 1589308200000, 1589394600000, 1589481000000, 1589567400000, 1589653800000, 1589740200000, 1589826600000, 1591122600000]
arr2 = [90.05, 98.0225, 99.8231, 99.3969, 73.45, 68.356, 55.123, 100, 68.75, 98.02430 ]

console.log(arr1.map((el, i) => [ el, arr2[i] ]))
