 There is a view helper method `react_component`. It is designed to work with `react_ujs` and takes a React class name, properties, and HTML options as arguments:
 
 ```ruby
-react_component('HelloMessage', :name => 'John')
+react_component('HelloMessage', name: 'John')
 # <div data-react-class="HelloMessage" data-react-props="{&quot;name&quot;:&quot;John&quot;}"></div>
 ```
 
 By default, a `<div>` element is used. Other tag and HTML attributes can be specified:
 
 ```ruby
-react_component('HelloMessage', {:name => 'John'}, :span)
+react_component('HelloMessage', {name: 'John'}, :span)
 # <span data-...></span>
 
-react_component('HelloMessage', {:name => 'John'}, {:id => 'hello', :class => 'foo', :tag => :span})

 This will return the fully rendered component markup, and as long as you have included the `react_ujs` script in your page, then the component will also be instantiated and mounted on the client.
