/**
 * Returns the first element of the list which matches the predicate, or

 * Dispatches to the `find` method of the second argument, if present.
 *
 * Acts as a transducer if a transformer is given in list position.

 * @func
 * @memberOf R
 * @since v0.1.0
 * @category List
 * @sig (a -> Boolean) -> [a] -> a | undefined
 * @param {Function} fn The predicate function used to determine if the element is the

 * @param {Array} list The array to consider.
 * @return {Object} The element found, or `undefined`.

 * @example
