/**
 * Recursively merges own and inherited enumerable string keyed properties of source
 * objects into the destination object. Source properties that resolve to undefined
 * are skipped if a destination value exists. Array and plain object properties are
 * merged recursively. Other objects and value types are overridden by assignment.
 *
 * @param object - The destination object
 * @param sources - The source objects
 * @returns The destination object
 *
 * @example
 * ```ts
 * const object = {
 *   'a': [{ 'b': 2 }, { 'd': 4 }]
 * };
 *
 * const other = {
 *   'a': [{ 'c': 3 }, { 'e': 5 }]
 * };
 *
 * merge(object, other);
 * // => { 'a': [{ 'b': 2, 'c': 3 }, { 'd': 4, 'e': 5 }] }
 * ```
