Question

I have a multi dimensional array that has 3 elements in each index.

Example [[bob,12,white],[alex,2,hispanic]]

How can I sort the array by the integer age (middle value)?

Take a look at Array.prototype.sort. You can pass a function to determine how your array should be sorted.

const sorted = [
  ['bob',12,'white'],
  ['alex',2,'hispanic']
].sort((a, b) => a[1] - b[1]) // sorts by integer age asc

console.log(sorted)
