/**

* The base implementation of `_.find`, `_.findLast`, `_.findKey`, and `_.findLastKey`,
|
|
* without support for callback shorthands and `this` binding, which iterates
|
|
* over `collection` using the provided `eachFunc`.
|
|
*
|
|
* @private
|
|
* @param {Array|Object|string} collection The collection to search.
|
|
* @param {Function} predicate The function invoked per iteration.
|
|
* @param {Function} eachFunc The function to iterate over `collection`.
|
|
* @param {boolean} [retKey] Specify returning the key of the found element
|
|
* instead of the element itself.
|
|
* @returns {*} Returns the found element or its key, else `undefined`.
