/**
 * Creates a flattened array of values by running each element in `collection`
 * thru `iteratee` and flattening the mapped results. The iteratee is invoked
 * with three arguments: (value, index|key, collection).
 *
 * @since 5.4.0
 * @category Collection
 * @param collection The collection to iterate over.
 * @param iteratee The function invoked per iteration.
 * @returns Returns the new flattened array.
 * @see [[flatMapDeep]],[[flatMapDepth]],[[flatten]],[[flattenDeep]],[[flattenDepth]],[[map]],[[mapKeys]],[[mapValues]]
 * @example
 *
 * ```js
 * function duplicate(n) {
 *   return [n, n]
 * }
 *
 * flatMap([1, 2], duplicate)
 * // => [1, 1, 2, 2]
 * ```
