3.4 What is a view folder?

Once you've successfully started your first simulation, you should be able to find the folder for this new project in the phetsims directory. In our case, it is called newton-raphson

But wait, I smell another very important question in the air

Question: What even is a view folder? What is it all about?

Answer: A view folder contains all the JavaScript files that represent the visual components that are going to end up on the simulation webpage. When you first start a new simulation all you will have are the default files and so the only file present inside the view folder at this time would be NewtonRaphsonScreenView.js. This file is responsible for putting all the components together to make the simulation work the way you want it to. (To learn more about how to work with this file, See Working with ScreenView to put all the components together)

Question: Where can I find it? 

Answer: The pathing for finding the view folder should be as follows: phetsims/newton-raphson/js/newton-raphson/view. This is the folder you're looking for to start developing.

Once we're done with this tutorial, the view folder would look something like this with all the files:
