What each file is actually doing

• /node_modules where your downloaded node module files go

• /public things in here are not compiled or minified by webpack (https://medium.com/@jenniferdobak/the-public-folder-and-favicons-in-create-react-app-8dc2cc1d492b)

  • favicon the icon that will appear in the tab of the browser

  • index.html this is our html template and react will inject the html code into the div with the id of root

If you keep my commands, you will remain in my love, just as I have kept my Father’s commands and remain in his love. I have told you this so that my joy may be in you and that your joy may be complete. My command is this: Love each other as I have loved you. Greater love has no one than this: to lay down one’s life for one’s friends. 14 You are my friends if you do what I command. I no longer call you servants, because a servant does not know his master’s business. Instead, I have called you friends, for everything that I learned from my Father I have made known to you. You did not choose me, but I chose you and appointed you so that you might go and bear fruit—fruit that will last—and so that whatever you ask in my name the Father will give you. This is my command: Love each other.",
