Enumerable is a collection of iteration method, a Ruby module and a great part of what makes ruby a great programming language. In this project, we try to customize some of the Ruby enumerable functions.

• Clone this Repo
• Navigate to project Directory
• Now, to test each function go to the end of the page and do the following.

• For my_each

[1, 2, 3, 5].my_each { |x| p x }

• Output

=> 1
=> 2
=> 3
=> 5

• For my_each_with_index

[1, 2, 3, 5].my_each_with_index { |x, y| puts "#{x} at #{y}" }

• Output

=> 1 at 0
=> 2 at 1
=> 3 at 2
=> 5 at 3

• For my_select

[1, 2, 3, 4].my_select { |x| x % 2 == 0}

• Output

=> [2, 4]

• For my_all

['alpha', 'apple', 'allen key'].my_all?{ |x| x[0] == 'a' }

• Output

=> true

• For my_any

['alpha', 'apple', 'allen key'].my_any?{ |x| x[-1] == 'y' }

• Output

=> true

• For my_none

['Alpha', 'Apple', 'Allen key'].my_none?{ |x| x[0] == 'z' }

• Output

=> true

• For my_count

arr = [1, 2, 3, 4]
arr.my_count { |i| i%2==0}

• Output

=> 2

• For my_map

[1,2,3,4,4,7,7,7,9].my_map { |i| i*4 }

• Output

=> [4, 8, 12, 16, 16, 28, 28, 28, 36]

• For my_inject

[1,2,3,4,4,7,7,7,9].my_inject(0){|running_total, item| running_total + item }

• Output

=> 44
