How to share variables between files in Node.js?

const name = "foobar";

exports.name = name;

to export the name variable in module.js by assigning it to exports.name.

And then in main.js, we write

main.js

const myModule = require('./module');

const name = myModule.name;

to call require to include the module.js module and assign the exported contents to myModule.

And then we get the exports.name value with myModule.name,
