Lodash_.xorBy method is similar to the _.xor() method except that it accepts iteratee which is invoked for each element of each array to generate the criterion by which they are compared. Order of result values which is determined by the order they occur in the arrays.
Syntax:
_.xorBy(arrays, iteratee);
Parameters:
- arrays: This parameter holds the arrays to inspect.
- iteratee: This parameter holds the iteratee invoked per element and is invoked with one argument (value).
Return Value:
This method returns the new array of filtered values.
Example 1: In this example, we are using the lodash _.xorBy() method for printing the xor of two arrays having each iteration with Math.floor in the console.
// Requiring the lodash library const _ = require( "lodash" );
// Original array let x = _.xorBy([3.1, 1.3, 4.6], [3.3, 3.4], Math.floor);
let y = _.xorBy([4.1, 2.3, 7.6], [4.3, 7.4], Math.floor);
// Use of _.xorBy() method let gfg = _.xorBy(x); let gfg2 = _.xorBy(y); // Printing the output console.log(gfg); console.log(gfg2); |
Output:
[ 1.3, 4.6 ]
[ 2.3 ]
Example 2: In this example, we are using the lodash _.xorBy() method for printing the xor of two arrays in the console.
// Requiring the lodash library const _ = require( "lodash" );
// Original array let x = _.xorBy([{ 'x' : 11 }],
[{ 'x' : 12 }, { 'x' : 11 }], 'x' );
let y = _.xorBy([{ 'x' : 11.2 }],
[{ 'x' : 12.2 }, { 'x' : 56.3 },
{ 'x' : 38.21 }, { 'x' : 11.2 }], 'x' );
// Use of _.xorBy() method // The `_.property` iteratee shorthand let gfg = _.xorBy(x); let gfg3 = _.xorBy(y); // Printing the output console.log(gfg); console.log(gfg3); |
Output:
[ { x: 12 } ]
[ { x: 12.2 }, { x: 56.3 }, { x: 38.21 }]
Example 3: In this example, we are using the lodash _.xorBy() method for printing the xor of two arrays having in the console.
// Requiring the lodash library const _ = require( "lodash" );
// Original array let x = _.xorBy([ 'p' ], [ 'q' ,
'r' , 's' , 'p' ]);
let y = _.xorBy([ 'tee' ], [ 'tee' ,
'cee' , 'dee' , 'bee' , 'eee' ]);
// Use of _.xorBy() method // The `_.property` iteratee shorthand let gfg = _.xorBy(x); let gfg3 = _.xorBy(y); // Printing the output console.log(gfg); console.log(gfg3); |
Output:
['q', 'r', 's' ]
['cee', 'dee', 'bee', 'eee' ]
Note: This code will not work in normal JavaScript because it requires the library lodash to be installed.
