Export
Here I oppose three different ways to export modules on node.js
Lets say we want to export three functions from a file called count.js
var counter = function(arr){
return 'There are '+ arr.length + ' elements';
}
//This can be done by using backticks
var adder = function(a,b){
return `The sum of two numbers is ${a+b}`;
}
var pi = 3.142;
First way
//Export
module.exports.counter = counter;
module.exports.adder = adder;
module.exports.pi = pi;
