Sort a json data based on a some json value in angular2

var people = [
   {
    "FirstName": "Adam" ,
    "Order": 3
   },
   {
    "FirstName": "Baron" ,
    "Order": 1
   },
   {
    "FirstName": "Ashton" ,
    "Order": 4
   },
   {
    "FirstName": "Kara" ,
    "Order": 2
   }
];
function sortJSON(data, key) {
    return data.sort(function (a, b) {
        var x = a[key];
        var y = b[key];
        return ((x < y) ? -1 : ((x > y) ? 1 : 0));
    });
}

var people2 = sortJSON(people, 'Order');
console.log("JSON",JSON.stringify(people2));

You can use pipe, Sorting

*ngFor="let option of options | orderBy:'Order'"

You could also do this with Lodash:

import * as _ from 'lodash';

_.sortBy(people, p => p.Order);

The advantage is that is also comes with a lot more functionality that can be very handy. Just be mindful of what you import from it, so not to bloat your output bundle.

Don't use pipes for sorting. Snippet from the Pipes documentation:

Appendix: No FilterPipe or OrderByPipe

Angular doesn't provide pipes for filtering or sorting lists. Developers familiar with AngularJS know these as filter and orderBy. There are no equivalents in Angular.

This isn't an oversight. Angular doesn't offer such pipes because they perform poorly and prevent aggressive minification. Both filter and orderBy require parameters that reference object properties. Earlier in this page, you learned that such pipes must be impure and that Angular calls impure pipes in almost every change-detection cycle.
