# Advanced Building Blocks - Enumerable Methods
> In this project, I implemented my own version of Ruby's enumerable methods. I created them in a way that they return the same results as the original when they are called.
Below are the methods implemented
- each
- each_with_index
- select
- all?
- any?
- none?
- count
- map
- inject
## Built With
- Ruby
## Getting Started
- Clone this repo on your local machine
- Run the command `bundle install` in your terminal
- Insert the lines below any where in your main.rb file to text the methods
```
hash = Hash.new
%w(cat dog wombat).my_each_with_index { |item, index|
hash[item] = index
}
p hash
p [1,2,3,4,5].my_select { |num| num.even? }
p %w[ant bear cat].my_all? { |word| word.length >= 3 } #=> true
p %w[ant bear cat].my_all? { |word| word.length >= 4 } #=> false
p %w[ant bear cat].my_all?(/t/) #=> false
p [1, 2i, 3.14].my_all?(Numeric) #=> true
p [nil, true, 99].my_all? #=> false
p [].my_all? #=> true
p %w[ant bear cat].my_any? { |word| word.length >= 3 } #=> true
p %w[ant bear cat].my_any? { |word| word.length >= 4 } #=> true
p %w[ant bear cat].my_any?(/d/) #=> false
p [nil, true, 99].my_any?(Integer) #=> true
p [nil, true, 99].my_any? #=> true
p [].my_any? #=> false
p %w{ant bear cat}.my_none? { |word| word.length == 5 } #=> true
p %w{ant bear cat}.my_none? { |word| word.length >= 4 } #=> false
p %w{ant bear cat}.my_none?(/d/) #=> true
p [1, 3.14, 42].my_none?(Float) #=> false
p [].my_none? #=> true
p [nil].my_none? #=> true
p [nil, false].my_none? #=> true
p [nil, false, true].my_none? #=> false
ary = [1, 2, 4, 2]
p ary.my_count #=> 4
p ary.my_count(2) #=> 2
p ary.my_count{ |x| x%2==0 } #=> 3
p (1..4).my_map { |i| i*i } #=> [1, 4, 9, 16]
p (1..4).my_map { "cat" } #=> ["cat", "cat", "cat", "cat"]
p (5..10).my_inject(:+) #=> 45
p (5..10).my_inject { |sum, n| sum + n } #=> 45
p (5..10).my_inject(1, :*) #=> 151200
p (5..10).my_inject(1) { |product, n| product * n } #=> 151200
longest = %w{ cat sheeps bear }.my_inject do |memo, word|
memo.length > word.length ? memo : word
end
p longest #=> "sheeps"
p multiply_els([2,4,5]) #=> 40
```
