Difference between <% %> and <%= %> in RoR [duplicate]

Question

What the difference between

<% some code %> 

and

<%= some code %> 

in RoR?

Answer 1

Think of it like this:

<% execute this code and display nothing %> 

and

<%= execute this code and display the result in the view %> 

So, for example you could do this:

<% @values = ['eenie', 'menie', 'miney', 'mo' ] %>
<% @values.each do |value| %>
  The current value is <%= value %>!
<% end %>
