We have been stalled on ESLint 3.8.0 for some time. Current ESLint is 3.13.0. We have been unable to upgrade because of more aggressive reporting on some rules, including indentation. ESLint configuration options and bugfixes are now such that we can reasonably upgrade.

/**

* This method is like `_.flatMap` except that it recursively flattens the

* mapped results up to `depth` times.

* @static
|
|
* @memberOf _
|
|
* @since 4.7.0

* @category Collection
|
|
* @param {Array|Object} collection The collection to iterate over.
|
|
* @param {Function} [iteratee=_.identity] The function invoked per iteration.
|
|
* @param {number} [depth=1] The maximum recursion depth.
|

* @returns {Array} Returns the new flattened array.

* function duplicate(n) {
