HELLO WORLD GCI TASK

node.js module that prints "hello world" created for google code in.

How to use it?

There are two ways to use module:

first - just run the function in main.js!

The main.js file contain:

function printHello(){
    console.log('hello world')
}
module.exports = {printHello}

To see hello world in the console you must run the function printHello

function printHello(){
    console.log('hello world')
}
module.exports = {printHello}

And voila! We see hello world in our console!

second way - use it as node module

Our printHello function is in main.js module because of module.exports = {printHello} line. So we can easily use it in another file! We can see that is a CJS module - so we can access it in other file by requiring it.

So just create another file , and name it, for example foo.js. Then as I say, we can access to module by requiring it.

const helloModule = require('./main');
/* Assign module object to the constant, ./main works if our main.js file is in the same directory!*/

helloModule.printHello();
/*Just run the printHello function*/

Then , when we type node foo.js in terminal , we get hello world typed in console.
