Cool multiple sort function found online, that also handles reverse sorting.

multifield.sort.js

generateSortFn(props) {
    return function (a, b) {
      for (var i = 0; i < props.length; i++) {
        var prop = props[i];
        var name = prop.name;
        var reverse = prop.reverse;
        if (a[name] < b[name])
          return reverse ? 1 : -1;
        if (a[name] > b[name])
          return reverse ? -1 : 1;
      }
      return 0;
    };
  }

//LODASH Version - this handles nested objects
import * as _ from 'lodash';

export class ArrayHelper {
  public static multisort(array, props): any {

    let sortfunc = function (a, b) {
      for (var i = 0; i < props.length; i++) {
        let prop = props[i];
        let name = prop.name;
        let reverse = prop.reverse;
        let aVal = _.get(a, name);
        let bVal = _.get(b, name)
        if (aVal < bVal)
          return reverse ? 1 : -1;
        if (aVal > bVal)
          return reverse ? -1 : 1;
      }
      return 0;
    };
    array.sort(sortfunc);
  }
}


//Example
//let fn = this.generateSortFn([{ name: 'sortWeight', reverse: true }, { name: 'title'}]);
// arr.sort(fn)
