embedded ruby syntax "<%= .. %>" in rails

Question

Am I correct with the idea below regarding ERB template? any advice would be really appreciated.

Is the embedded ruby syntax with an equal sign "<%= %>" intended to render some output? while the one without the equal sign "<% %>" doesn't.

Answer 1

When you use <%= %> you render the expression value to your output. While <% %> is simply to write some Ruby code that won't be rendered to final output.
