how to access more then one function

Noticed that the getProfile was set to the get with:

 module.exports.get = getProfile;

and called on the app.js side with:

 const profile = require('./profile.js');
 const users = process.argv.slice(2);
 users.forEach(profile.get);

Say I have more then one function in the profile.js module. How would I access that as well if I could only call profile.get. and profile.get has already been assigned to getProfile.

Thank you

Nevermind after proceeding to the Questions after the video it made sense? Though I would readly love clarification. The:

 module.exports.get = getProfile;
 module.exports.say= getProfile;
 module.exports.getProfile = getProfile;

the get can be changed. I've tried replacing it with say, getProfile, and other words and it worked fine after accessing it on the app.js side. The get is a property being created then accessed in app.js using the below:

 users.forEach(profile.get);
 users.forEach(profile.say);
 users.forEach(profile.getProfile);

It also helps to think of module.exports as an object you're returning from the module. As such, if you have more than one export:

module.exports.get = getProfile;
module.exports.something = something;

You might consider rewriting like:

module.exports = {
  get: getProfile,
  something: something
}

Tim, so you mean to say that the exports can be formatted to a JSON Object? Afterwards are there any steps to do? Let say for example I want to export 3 methods

module.exports = {
  get: getName,
  get: getAge,
  get: getAddress
}

//module.start export() or something ? or the above code is enough? Thanks. Also by doing export, does it mean that all exported functions are visible to all other JS files?
