• .sort, .sortBy - sort arrays, lists, and streams (by attribute)
• .minBy, .maxBy - find the minimum/maximum in arrays, collections, iterables, and streams
• .groupBy - group arrays, collections, iterables, and streams by attribute
• .exists, .forall - test if one/all element(s) of an array, a collection, an iterable, or a stream hold(s) a given condition
• .reverse - reverse arrays, lists, and strings
• .concat - concatenate arrays, collections, and streams
• .join, .mkString - join the elements (strings) of an array, a collection, an iterable, or a stream into one string by using a given separator
• .stream - convert iterable to stream
• .map - map the entries of lists, sets, and maps
• .mapKeys - map the keys of a map
• .mapValues - map the values of a map
• .getOrElseUpdate - return the map value of a given key or compute it and return it
• .filter - filter the elements of lists, sets, maps, and iterables
• .reduce - reduce the elements of arrays, collections, and iterables
• .fold - reduce the elements of arrays, collections, and iterables by using a neutral element (similar to Scala fold)
• .find - find an element in arrays, collections, iterables, and streams
• .take - take a certain number of elements from a stream
• .drop - skip a certain number of elements from a stream
• .size - get the length or an array
• .get - get an element of an array by index
• .first, .head - get first element of a list, or an array
