Array Extensions

// Return a random element
[😀,🤡,❤️,💋].sample() // => 💋
// Return n random elements
[😀,🤡,❤️,💋].sampleSize(2) // => [🤡, 💋]
//Drop elements that passes the predicate from the beginning to end
[1, 2, 3, 4, 5].dropWhile { $0 < 3 } // => [3, 4, 5]
//And YES you can use method chaining too 👍
[1, 2, 3, 4, 5].dropWhile { $0 < 3 }.some {$0 % 2 == 0} // => true
//Check if all elements in the array passed the condition
[0, 11, 28, 10].every { $0 % 2 == 0 } // => false
//Check if one of the element passes the condition
[0, 11, 28, 10].some { $0 % 2 != 0 } // => true
//Find index of the last number which predicate return true for.
[1, 2, 3, 4, 5].findLastIndex {$0 % 2 == 0} // => 3 
//Group common elements from an array to a dictionary of [Hashable : [Element]]
[1, 2, 3, 4, 5].groupBy { $0 % 2 == 0 ? "even" : "odd"} // => ["even": [2,4], "odd": [1,3,5]]
