def call(method:, params:,  **_)
  @routes.each do |(pattern, block)|
    next if pattern != method

    return block.call(*params)
  end

  raise NoMethodError, "Undefined method '#{method}'"
end

#handle(pattern, &block) ⇒ Object

pattern - Right now just a String that 1-to-1 matches the ‘method` block - Block to call with the `params`
