Lodash - differenceWith method

Syntax

_.differenceWith(array, [values], [comparator])

This method is like _.difference except that it accepts comparator which is invoked to compare elements of array to values. The order and references of result values are determined by the first array. The comparator is invoked with two arguments: (arrVal, othVal).

Arguments

• array (Array) − The array to inspect.

• [values] (...Array) − The values to exclude.

• [comparator] (Function) − The comparator invoked per element.

Output

• (Array) − Returns the new array of filtered values.

Example

var _ = require('lodash');
var objects = [{ 'x': 4, 'y' : 2 }, { 'x': 1 }];
var result = '';

result = _.differenceWith(objects, [{ 'y': 2, 'x': 4 }], _.isEqual);
console.log(result);
