The _.xorWith() method is similar to _.xor() method except that it accepts comparator which is invoked to compare elements of arrays. Order of result values which is determined by the order they occur in the arrays.
Syntax:
_.xorWith([arrays], [comparator])
Parameters: This method accepts two parameters as mentioned above and described below:
- [arrays]: This parameter holds the arrays to inspect.
- [comparator] (Function): This parameter holds the comparator invoked per element and is invoked with two arguments(arrVal, othVal).
Return Value: This method is used to returns the new array of filtered values.
Example 1: Here, const _ = require(‘lodash’) is used to import the lodash library in the file.
javascript
// Requiring the lodash library const _ = require("lodash"); // Original array var objects = [{ 'x': 3, 'y': 4 }, { 'x': 4, 'y': 3 }]; var others = [{ 'x': 3, 'y': 3 }, { 'x': 3, 'y': 4 }]; // Use of _.xorWith() // method let gfg = _.xorWith(objects, others, _.isEqual); // Printing the output console.log(gfg); |
Output:
[{ x: 4, y: 3 }, { x: 3, y: 3 }]
Example 2:
javascript
// Requiring the lodash library const _ = require("lodash"); // Original array var objects = ([ 23, 34, 98 ], [ 34, 23 ]); var obj = ([ 4, 6 ], [4, 34, 6, 98 ]); // Use of _.xorWith() // method let gfg = _.xorWith(objects, obj, _.isEqual); // Printing the output console.log(gfg); |
Output:
[ 23, 4, 6, 98 ]
Example 3:
javascript
// Requiring the lodash library const _ = require("lodash"); // Original array var obj1 = ([ 'p', 'q', 'r' ], [ 'u', 's', 't', 'u' ]); var obj2 = ([ 'p', 'q', 'u', 's' ], [ 't', 'r', 'u' ]); // Use of _.xorWith() method let gfg = _.xorWith(obj1, obj2, _.isEqual); // Printing the output console.log(gfg); |
Output:
[ 's', 'r' ]
Note: This code will not work in normal JavaScript because it requires the library lodash to be installed.
