 In Backbone, you might assign values from `options` to the model. Do not do this with React. Remember, `options` is `props`. 
 Therefore, it might be required to remove some items from the View's model.
 
+### Converting EJS template to JSX

+I will assume we're using EJS to be specific. JSX is not text, it's hidden JS tree construction expression, thus control structures must be transformed to functional form. In short, branches becomes logical expressions, loops becomes `map` expressions. Expression must return single node or array, in the last case you're required to add `key` attribute.

 ### Use Existing Model as component's state
 
 If you already have one model, describing View's state (usual pattern is listening to model's `change` event and calling `this.render()`),
