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

In case you get here needing to do this with an array of objects, here is an adaptation of @Durgpal Singh's awesome answer:

const itemsArray = [
  { name: 'Anne', id: 'a' },
  { name: 'Bob', id: 'b' },
  { name: 'Henry', id: 'b' },
  { name: 'Andrew', id: 'd' },
  { name: 'Jason', id: 'c' },
  { name: 'Thomas', id: 'b' }
]

const sortingArr = [ 'b', 'c', 'b', 'b', 'a', 'd' ]

Object.keys(itemsArray).sort((a, b) => {
  return sortingArr.indexOf(itemsArray[a].id) - sortingArr.indexOf(itemsArray[b].id);
})
