I built my first javascript app using HTML and CSS as well. It is a basic tip calculator. I've pushed my code to my GIT but when i click on website deployed its just the README file. I have a feeling I need to use Node.js but after the basic reading I did on it I have no idea how to accomplish this. I just want to push the app to heroku or even just off the GIT page to see it in action on another device.
I tried running npm init and it created a package.JSON but every time i pushed to heroku the app would crash and give me an error stating it can not find the "start" script i input.
here's my github for the app, https://github.com/jaronow/tip-calculator. I would appreciate some basic guidance or a link to somewhere i can learn how to accomplish this task
