You could take the index of the tags of order_basis assortorder by using an object with this data.

var order_basis = [{ tag: 'vip' }, { tag: 'home' }, { tag: 'work' }],
    main_data = [{ tag: 'work', name: 'sample', contact: '0987654', email: '[email protected]' }, { tag: 'home', name: 'sample', contact: '0987654', email: '[email protected]' }, { tag: 'home', name: 'sample', contact: '0987654', email: '[email protected]' }, { tag: 'work', name: 'sample', contact: '0987654', email: '[email protected]' }, { tag: 'vip', name: 'sample', contact: '0987654', email: '[email protected]' }],
    order = {};

order_basis.forEach(function (o, i) { order[o.tag] = i + 1 });

main_data.sort(function (a, b) {
    return order[a.tag] - order[b.tag];
});

console.log(main_data);

You can sort the main function based on the order_basis array.

function getFormatted(main, order_basis){
  order_basis = order_basis.map(x => x.tag);
  return main.sort(function(a, b){
    if(order_basis.indexOf(a.tag) > order_basis.indexOf(b.tag))
      return 1;
    return -1;
  });
}

var order_basis = [{ tag: 'vip' }, { tag: 'home' }, { tag: 'work' }],
main_data = [{ tag: 'work', name: 'sample', contact: '0987654', email: '[email protected]' }, { tag: 'home', name: 'sample', contact: '0987654', email: '[email protected]' }, { tag: 'home', name: 'sample', contact: '0987654', email: '[email protected]' }, { tag: 'work', name: 'sample', contact: '0987654', email: '[email protected]' }, { tag: 'vip', name: 'sample', contact: '0987654', email: '[email protected]' }];


console.log(getFormatted(main_data, order_basis));

.as-console-wrapper { max-height: 100% !important; top: 0; }
