== How to use Require ==

Require will cache objects after it calls them, kind of like a singleton pattern.

To build out an object that require can grab there are a couple of different ways.

The following way will create an object based on a function so it can have private variables.

example.js
const exampleService = (function() {
const self = this;

self.print = function() {
console.log('...');
}

return this;

})();
module.exports = exampleService;

Another way is to create a kind of JSON object with functions.

example.js
const exampleService = {
name: 'example',
print: function() {
console.log('...');
}

};
module.exports = exampleService;

	module.exports = exampleService;		module.exports = exampleService;
		+
		+
		+	Then you can call them from your script like so.
		+	const exampleService = require('./service/example');
		+	exampleService.print();
		+
		+	You don't need to add the .js but I think you have to start with '.' directory.
