You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: children_spec.rb
    path of file: ./repos/hyper-react/spec/react
    
    the code of the file until where you have to start completion: require 'spec_helper'

describe 'React::Children', js: true do
  describe 'with multiple child elements' do
    before :each do
     
    
          def self.get_children
            component = Class.new do
              include React::Component
              def render
                div { 'lorem' }
              end
            end
            childs = [ React.create_element('a'), React.create_element('li') ]
            element = React.create_element(component) { childs }
            el_children = element.to_n.JS[:props].JS[:children]
            children = React::Children.new(el_children)
            dom_el = JS.call(:eval, "document.body.appendChild(document.createElement('div'))")
            React.render(element, dom_el)
            children
          end
        end
