About node.js

These days everybody talks about node.js. Some of them boast about what cool things they did with node.js. Well, I need to catch up with these guys but I don't want to spend too much time learning node.js. So I set out a challenge myself to find out more about node.js in a short period of time.

So I downloaded node.js and all ready to go!

My first experiment with node

1. On my windows PC, I created a file test.js under C:\node-examples folder
2. I added the following line in test.js:
console.log("testing node");
3. From command prompt, I ran the command "node test.js" and "testing node" came up.
C:\node-examples>node test.js
4. Viola! I was able to run my JavaScript file from command prompt using node.

My second experiment with node

1. I modified test.js so that now it has the following content:
function printLine(){
       console.log("printing from node");
}
console.log(printLine());
2. From command prompt, I ran the command "node test.js" and "printing from node" came up. Nice!!
C:\node-examples>node test.js

Notes:

There is this site http://code.tutsplus.com/tutorials/nodejs-for-beginners--net-26314 where they have a simple but good tutorial on node.js! I am going to dive into that right away!
