Javascript - sort array based on another array

Question

Is it possible to sort and rearrange an array that looks like this:

itemsArray = [ 
    [\'Anne\', \'a\'],
    [\'Bob\', \'b\'],
    [\'Henry\', \'b\'],
             


        

Answer 1

let a = ['A', 'B', 'C' ]

let b = [3, 2, 1]

let c = [1.0, 5.0, 2.0]

// these array can be sorted by sorting order of b

const zip = rows => rows[0].map((_, c) => rows.map(row => row[c]))

const sortBy = (a, b, c) => {
  const zippedArray = zip([a, b, c])
  const sortedZipped = zippedArray.sort((x, y) => x[1] - y[1])

  return zip(sortedZipped)
}

sortBy(a, b, c)
