[Ruby] Count an even number in an array using the even? Method

Create a method that counts and outputs an even number from the values in the array. Use the ʻeven? Method` to determine if the value is even.

Output example: count_evens([2, 1, 4, 6]) → 3

Answer 1

def count_evens(nums)
  count = 0
  nums.each do |num|
    if num.even?
      count += 1
  puts count

Answer 2

It's a bit confusing compared to Answer 1, but ...

def count_evens(nums)
  result = []
  nums.each do |num|
    if num.even?
      result << num
  puts result.length
