apple_picker.rb

# Create a method, apple_picker, that will pick all the apples out of an array. Implement it with collect and then implement it with select. Write a sentence about how select differs from collect.

fruits = ["orange", "banana", "apple", "orange", "apple", "banana", "orange", "apple"]

#with collect
def apple_picker_collect(array)
  array.collect do |array_element|
    array_element if array_element == "apple"
  end
end

puts apple_picker_collect(fruits).compact

puts #add a space between the two methods

#with select
def apple_picker_select(array)
  array.select do |array_element|
    array_element if array_element == "apple"
  end
end

puts apple_picker_select(fruits)

# The difference between the collect and select methods:
# Collect returns a new array containing everything in the original block but modified as per the collect block, so in the above it was necessary to use compact to remove all the fruits which returned nil.
# Select returns only that which returned true as per the select block, which made the compact call unnecessary.
