dynatrace-cordova-outsystems-plugin/node_modules/lodash/unionWith.js

This plugin gives you the ability to use the Dynatrace instrumentation in your hybrid application (Cordova, Ionic, ..). It uses the Mobile Agent, the JavaScript Agent and the Javascript Bridge. The Mobile Agent will give you all device specific values con

/**
 * This method is like `_.union` except that it accepts `comparator` which
 * is invoked to compare elements of `arrays`. Result values are chosen from
 * the first array in which the value occurs. The comparator is invoked
 * with two arguments: (arrVal, othVal).
 *
 * @static

 * @since 4.0.0
 * @category Array
 * @param {...Array} [arrays] The arrays to inspect.
 * @param {Function} [comparator] The comparator invoked per element.
 * @returns {Array} Returns the new array of combined values.
 * @example
 *
 * var objects = [{ 'x': 1, 'y': 2 }, { 'x': 2, 'y': 1 }];
 * var others = [{ 'x': 1, 'y': 1 }, { 'x': 1, 'y': 2 }];
 *
 * _.unionWith(objects, others, _.isEqual);
 * // => [{ 'x': 1, 'y': 2 }, { 'x': 2, 'y': 1 }, { 'x': 1, 'y': 1 }]
