title: How to publish my java script project with multiple files as an npm package?
body: <p>I was building a toolkit for a personal project and had arranged my tools (JavaScript functions) in separate files. For example, if the name of the folder was 'Calculator', the files would be 'Addition', 'Subtraction' ... However, when I looked online on how to publish to npm, all the tutorials say to have a single index.js file. How do I work around this?</p>
