how to use export module in node js code example

Example 1: What is the syntax to export a function from a module in Node.js

function foo() {}
function bar() {}

// To export above functions:
module.exports = foo;
module.exports = bar;

// And in the file you want to use these functions,
// import them like this:
const foo = require('./module/path');
const bar = require('./module/path');

Example 2: module.exports multiple functions

module.exports = function(firstParam) { console.log("You did it"); },
module.exports = function(secondParam) { console.log("Yes you did it"); }, 
// This may contain more functions
