  ['name' => 'Alok', 'age' => 25],
]);
 
$sorted = $collection->sortBy('age');
$sorted->values()->all();
 
/*
  [
    ['name' => 'Anmol', 'age' => 20],
    ['name' => 'Alok', 'age' => 25],
    ['name' => 'Krishan', 'age' => 28],

$sorted->values()->all();
 
/*
  [
    ['title' => 'Item 1'],
    ['title' => 'Item 3'],
    ['title' => 'Item 12'],
  ]

$sorted = $collection->sortBy([
  ['name', 'asc'],
  ['age', 'desc'],
]);
$sorted->values()->all();
 
/*
  [
    ['name' => 'Alok', 'age' => 25],
    ['name' => 'Anmol', 'age' => 20],
