Advanced Building Blocks - Enumerable Methods

[Collaborative project]

In this project, we are implementing our version of Ruby's enumerable methods.

Covered methods

• #my_each
• #my_each_with_index
• #my_select
• #my_all?
• #my_any?
• #my_none?
• #my_count
• #my_map
• #my_inject
• #multiply_els which multiplies all the elements of the array together by using #my_inject, e.g. multiply_els([2,4,5]) #=> 40

Built With

• Ruby

Getting Started

Clone

git clone git@github.com:marijanbrvar/Enumerables.git

To get a local copy up and running, follow these simple example steps.

1. Open a terminal window and enter fit clone https://github.com/marijanbrvar/BubbleSort.git
2. Make your new cloned directory your active directory
3. Currently, you are in the "development branch."
4. Change your current branch to enumerables branch git checkout enumerables
5. Use irb to test folder with following console command irb -I . -r enumerable.rb
6. Once you are in the irb console, use the syntax to invoke the method stated below

Prerequisites

Ruby installed localy

Usage

Use IRB to test the code

my_select

[1,2,3,4,5,6].my_select(&:even?)
=> [2,4,6]

my_all?

[1,2,3,4,5,6].my_all?(&:even?)
=> false

my_any?

[1,2,3,4,5,6].my_any?(&:odd?)
=> true

#my_none?

[1,2,3,4,5,6].my_none?(&:odd?)
=> true

#my_count

[1,2,3].my_count
=> 3
[1,2,3].my_count { |x| x > 1}
=> 2

#my_map

[1,5].my_map { |x| x * 2 }
=> [2, 10]

[1,2,3,4,5].my_map Proc.new { |x| x * 4 }
=> [4,8,12,16,20]

#my_inject

(5..10).my_inject(:+)
=> 45
(5..10).my_inject { |sum, n| sum + n }
=> 45

#multiply_els

[1,2,4,5,6].my_multiply_els
=> 240
