Wanderlust: please help me with step 29. I don't understand how to console.log renderVenues();

Hello. Please help me to understand how I could figure out step 29 on my own.
I got into this project by doing the JavaScript introduction and I am a bit lost about what is happening here.

Specifically:

  1. in step 29 of Wanderlust project, it suggests I can console.log venueIcon. I couldn’t figure out how to do so. I did console.log and inspected with F12 before, however, this time it is not showing up in console (as did before while calling get venues and console.log(venues). How exactly can I see the VenueIcon object?

  2. what are all those variables with $ prefix? what is this $submit.click? I don’t understand when or how renderVenues() is been called.

I should jump right into the web dev path after finishing JavaScript intro. However, what should I look for to get used to this environment? Any tip pointing out in the right direction is appreciated.

Many thanks
