I am just getting into using the theme customizer in WordPress. I found a great answer on this site about adding a slider and I got it working just fine. I was reading in the codex about the theme-customizer and it says that after you add your settings, you need to add to the theme-customizer.js file to update your settings. Does this really need to be done? I noticed that without adding my settings to this file that the slider images that I just got working seem to work just fine. So I am a little confused on this step. I can't even find the information that the codex is talking about in the default theme.
Even with these settings. The codex says that this stage is optional. I have added 3 photo uploads for a slider. Just to test out the customizer. The theme updates in real time without adding this kind of information about my new controls
