What is Webpack?
Webpack is a module bundler for JavaScript as well as HTML applications. It grabs modular pieces of code compartmentalized in folders. Followed by reconstituting them into a compiled form. Then it's read as a whole by the application. You must be thinking, "Why break up a working code?" As your code scales, so does its complexity. Finding a correlation between each block becomes a challenge.
I worked in marketing and data analysis. After a long time, I decided to change career and leave my 8 to 5 job, to pursue a remote job and start a business of my own. After this point, it's difficult to decide where to look for information and what language to start learning first. If you don’t have any previous knowledge this could be an impediment to continue with your goal. And a waste of your time trying to find the right resources to start.

After completing the first built of our rails app application, I decided to take it out for a spin. Using Ruby commands that were initially tested on rails console, I built a seed file to populate the database. There were 2 reasons to seed the database. The first was to get an aesthetic feel of the app filled with data. The second was to see how would the app would scale visually with a huge amount of data.

Imagine you have six images on your home page. You might proceed with loading the images separately. After all, they are six different images and to be used in six different places. And you might be right ... from your perspective. You also know that loading six different images will force the browser to make six different HTTP requests to the server. And each time it makes a request, a few milliseconds gets added to your page loading time. That's bad news if you have fifty images.
In the first quarter of 2020, I had the experience of being in a short term advisory role for a company that had built a type of Linkedin product for a specific vertical market. They had done a valiant job, but it was clear that scalability was a problem and they had created a problem for themselves by having used MongoDB as the datastore.
There is a mystical aura around password creation. Some kind of occult knowledge reached only by the distant cryptographic hermits who ascended to nirvana after decades of meditation on the Patagonian glaciers and liters of instant coffee.

A popular challenge that beginner programmers participate in is called 100 Days of Code. Although I never participated in it myself, I see countless tweets with screenshots and progress reports of people sharing bits of apps they made. 100 Days of Code is a great way to keep people in the programmer mindset. It gets them familiar with what it is like to code every day. Still, I wonder if it is the best approach for everyone. For them, One Game a Month could be a great alternative.

However these days I see that people are trying to introduce their kids to programming and looking for ways to make programming concepts more approachable. I think that using existing games people love is a great way to do just that. That is why I wanted to start this new coding for gamers blog series. In this tutorial I will show you how to do that by walking you through the process of extracting a feature from a video game called The Long Dark and recreating it on your own.
