The diffAssoc() function is used to compare two given collection and returns the values and their indices which are not present in the given collection. If key-value pair is given in the collection it compares and returns on the basis of keys specified.
Syntax:
diffAssoc( collection );
Parameters:
- collection: It is the collection given whose values are to be compared from the original array.
Return Value: It returns the values and their indices which are not present in the given collection.
Example 1: When an array is given as a collection
Javascript
// Importing the collect.js module. const collect = require('collect.js'); let array = ["a", "b", "c", "d", "e"]; let arr = ["a", "b", "q"]; // Making the collec1 let collec1 = collect(array); let collec2 = collect(arr); // Using diffAssoc() Function let aa = collec1.diffAssoc(collec2) // The output is so because c, d, e // are not present in collec2 // But are present in collec1 console.log("Output : ") console.log(aa.all()) |
Output:
Example 2: When object of key-value pair is given.
Javascript
// Importing the collect.js module. const collect = require('collect.js'); let obj1 = { "a": 1, "b": 12, "c": 3 }; let obj2 = { "a": 12, "d": 2, "c": 3 }; // Making the collec1 let collec1 = collect(obj1); let collec2 = collect(obj2); // Using diffAssoc() Function let aa = collec1.diffAssoc(collec2) // The output is so because a whose // value is 1 and b whose value is 12 // because are not present in collec2 // But are present in collec1 console.log("Output : ") console.log(aa.all()) |
