Requirement: Let us assume we called REST Web Service, which returned us multiple duplicate departmentId and departmentName, and I want to display only the unique combinations of departmentId and departmentName. Hence for such a case, we can pass the entire data into the JavaScript function and then filter out the duplicate data and return only the unique data.

Solution: For the solution of the above requirement we will use the below JavaScript code.

define([], function() {
  'use strict';

  var PageModule = function PageModule() {};

  PageModule.prototype.uniqueDepartmentDetails = function(result) {
    var uniqueResult = [];
    var final = [];
    if (result && result.length > 0) {
      for (var i = 0; i < result.length; i++) {
        if (!uniqueResult[result[i].departmentId]) {
            departmentId: result[i].departmentId,
            departmentName: result[i].departmentName,
          uniqueResult[result[i].departmentId] = 1;
    return final;
    return PageModule;

Hence, the solution to our requirement.
