// First Export from other file
export default exampleFunction;
// for multiple exports use:
module.exports =  { exampleFunction1, exampleFunction2 };

// Then we import in the file where we want to use our functions
import exampleFunction from "./otherFile.js";
// for multiple imports, we desctructure
