/**
 * Takes an array of objects and returns the last element in the array that has properties which match
 * all of those specified in the `compare` object. For example, if the compare object was: `{ scaleX: 0.5, alpha: 1 }`
 * then it would return the last item which had the property `scaleX` set to 0.5 and `alpha` set to 1.
 *
 * To use this with a Group: `GetLast(group.getChildren(), compare, index)`
 *
 * @function Phaser.Actions.GetLast
 * @since 3.3.0
 *
 * @generic {Phaser.GameObjects.GameObject[]} G - [items]
 *
 * @param {(array|Phaser.GameObjects.GameObject[])} items - The array of items to be searched by this action.
 * @param {object} compare - The comparison object. Each property in this object will be checked against the items of the array.
 * @param {number} [index=0] - An optional offset to start searching from within the items array.
 *
 * @return {?(object|Phaser.GameObjects.GameObject)} The last object in the array that matches the comparison object, or `null` if no match was found.
