/**
* 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 4.0.0
* @category Collection
* @param {Array|Object} collection The collection to iterate over.
* @param {Function} iteratee The function invoked per iteration.
* @returns {Array} Returns the new flattened array.
* @see flatMapDeep, flatMapDepth, flatten, flattenDeep, flattenDepth, map, mapKeys, mapValues
* @example
*
* function duplicate(n) {
* return [n, n]
* }
*
* flatMap([1, 2], duplicate)
* // => [1, 1, 2, 2]
