Grab first N elements from an array

Have you ever wanted to grab the first n elements from an array?

You might think to do something like this:

fruit = ["apple", "banana", "blueberry", "cherry", "dragonfruit"]

# Grab the first 3 elements of the array
fruit[0...3]
=> ["apple", "banana", "blueberry"]

Well you could just use Array#take and tell it how many elements you want to take:

fruit = ["apple", "banana", "blueberry", "cherry", "dragonfruit"]

# Grab the first 3 elements of the array
fruit.take(3)
=> ["apple", "banana", "blueberry"]

Bonus: There is also Array#take_while which takes a block and passes elements until the block returns nil or false

fruit.take_while {|f| f.length < 8 }
=> ["apple", "banana"]

fruit.take_while {|f| f.length < 10 }
=> ["apple", "banana", "blueberry", "cherry"]
