After changing sublayout code, do I need to do a Sitecore publish?

I change my code on my sublayout. What I should d开发者_StackOverflowo to see my changes modified on the sublayout output ? Do I have to smart publish ?

What is the difference betwen smart publish and incremental publish.

If you didn't change Sitecore items, you don't have to publish. Just recompile your code.
