Summary
Build a User Class that Can Be Passed a Block to Set Its Values.
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 = "test@test.com" end user.name # 'Jordan' user.email # 'test@test.com'
Should work, along with:
user = User.new user.name = "Jordan" user.email = "test@test.com" user.name # 'Jordan' user.email # 'test@test.com'
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.
