Exercise File
Exercise Description
In order to properly pass this coding exercise you’ll need to create a Ruby User class that is flexible enough to take a block along with the traditional data setting process..
Examples
user = User.new do |u| u.name = "Jordan" u.email = "[email protected]" end user.name # 'Jordan' user.email # '[email protected]'
Should work, along with:
user = User.new user.name = "Jordan" user.email = "[email protected]" user.name # 'Jordan' user.email # '[email protected]'
Real World Usage
Using blocks in Ruby is important when it comes to creating flexible interfaces for methods and classes. Additionally, a large number of Ruby methods optionally take a block, so it’s helpful to understand how the process works.
