nodeschool | : snowflake : My answers to the nodeschool.io problem sets

I'm wondering in principle how node.js works on a website that's running node code. I'm new to programming but I did manage to get node installed to practice with Angular and some Nodeschool stuff, however I don't think this is actually the whole story because the web server needs to have node and npm (maybe nvm) all installed in order to actually use any node code. Or am I misunderstanding how node works?

I guess I'm really looking for an understanding of the whole application of the node framework; what am I actually doing by running a practice program like the "Tour of Heros" Angular tutorial on my local machine, just testing it locally right? Because if I actually wanted it on my website I'd need to install node there and then run the framework on the server, from what I can gather...

Thanks for your time! I hope I made my confusion clear enough.

While I am working on a node project from nodeschool.io, one of the things I need to do is construct a date format, and make sure that is correctly formatted in accordance to how it is displayed. Here is the format: "YYYY-MM-DD hh:mm" I use the date object to grab the date info I need, then I gather it all into an array to create an easy for loop that will convert it to string to make certain formatting practices easier. One specific formatting practice I've been attempting to do is to append a "0" to month and day since the format requires two digits in month and day, however, the two numbers only have 1 digit since that is the current date. For some odd reason, the 0 will not be appended.

I am working through the nodeschool.io workshops and the second exercise of promise-it-wont-hurt is instructing me to install es6-promise.

Using my Windows 7 command prompt, I am typing npm install es6-promise (and some other variations) and I am getting the message.

Trying to slice array while taking args from command prompt as the array items. The problem is that the positional parameters for slicing do not work as I expect. How do I slice array taking params from prompt?

I am studying nodejs from freecodecamp and nodeschool. I was stuck several hours to find the mistake of my code and still I can't understand the difference.

It would be awesome if someone explain what is wrong with my code.

Learnyounode problem name FILETRED LS.

My Code

I am trying to solve the Juggling Async problem of learnyounode.

The following is what I have tried. But I am not getting desired output. I can find the solution by searching in google. But what I want is to learn node fundamentals. Can somebody direct me where I am going wrong?

I am learning node by doing learnyounode exercises from nodeschool. In the 8th exercise they ask to write a program which does the following:

• takes three URLs as arguments,
• collects data from responses,
• prints them to the console in the same order as in the arguments.

They briefly mention the existence of async libraries which help with counting callbacks but they also invite to complete the exercise without them. My initial solution then was the following:

I've been trying to run a simple Hello World app in node, thing is I'm using console.log to print to stdout instead of using a fancy http server or anything.

I am running NodeJS LTS, node v6.10.0 npm 4.3.0 on Windows 10 x64.

The script I'm running is basically just a console.log("Hello World");.

Now if I run this line from inside the node command line, it works just fine.

But if I try running putting it into a separate file and running it via node program.js where program.js is console.log("Hello World");

So, why I am getting this output:
