Tumblbug ranked first in the funding category with 11,688%, and Wadiz achieved 2,276% funding!
You can really become a developer in just 6 months of study!
An introductory coding guide that even non-majors can understand in no time.

We live in a daily life that is inseparable from digital technology.
We work on our smartphones, order from kiosks, and watch conferences held on the other side of the world on Zoom.
Recently, artificial intelligence, which once seemed distant, is naturally entering our daily lives, with the release of a conversational AI called ChatGPT.
As digital technology becomes more widespread, basic IT knowledge becomes more essential, and among these, coding skills are the most practical.

"The World's Easiest Coding Book" is an introductory book for those learning coding for the first time.
This book, which has already become a word-of-mouth hit as a coding e-book, has now been officially published, recording a funding achievement rate of 11,688% on Tumblbug and 2,276% on Wadiz.
The author, who was working in the fashion industry, decided to study coding to jumpstart her career, but was frustrated by the difficulty of the coding books available on the market.
However, I learned coding and development in my own way and joined an IT company.
Afterwards, he wrote this book with various know-hows and easy explanations for people who, like him, have difficulty coding.
This book will help non-majors who want to get a job as developers in the future, as well as IT workers who need to know coding to work with developers, acquire the fundamentals of coding.

A place called 'Time Cafe' has three employees and always follows the following procedure when selling coffee.
It follows the so-called procedural programming method.
Order coffee → Extract coffee → Prepare cup → Insert cup holder and prepare straw → Sell coffee

This procedure must be followed and the order must not be changed.
If one thing is not done right, you can't sell coffee.
This means that you cannot insert the cup holder in advance if the coffee extraction is not finished.
Let's assume that coffee must be sold only in that order.
It's frustrating.

If there aren't many guests, it can be processed quickly and without much difficulty using procedural methods.
But suddenly, customers start flocking to Time Cafe.
The three employees start to get confused and their paths start to get tangled.
Even if a customer who received coffee complains about the taste of the coffee, it is not just one person who is in charge of making the coffee, but they move to a nearby place, so they are so busy that they don't even know who made it.
You can't blame anyone for bad coffee.
It's becoming more and more of a mess.

Let's say you're building a house in the countryside.
Once the frame is built, materials are placed on top, and cement is applied, the shape of the house is completed.
But should we move in right away in this condition? No.
I need to do some interior design.
If there is no design on the outside or inside, it will look bleak and forbidding.
Likewise, even though I've worked hard on writing code, there are times when the tags feel too plain and boring.
Just like building a house, tags also need interior design.
This is precisely what CSS does. CSS 'decorates' tags.
Decorating a tag means designing additional effects such as font size, color, and shadow.

Primitive type variables and reference type variables occupy different storage spaces.
Primitive types are stored on the stack, and reference types are stored on the heap.
Let's compare this concept to desk drawers and lockers.

Think back to your school desks and lockers.
There was a drawer right under the desk.
In this space, I usually put books that I would take out and use right away, such as the books for today's study or the books for the next class.
Because it's easy to take out.
However, not only will it not fit large books, it will also take up little space.
It is convenient, but has the limitation of limited capacity.

But the lockers at the back of the classroom have the disadvantages of desk drawers as advantages.
The space is larger than a desk drawer, so it's good for storing heavy, large books.
The downside of lockers is that they are farther away than desk drawers, so it takes time to get books out, and you need to know the locker number to find a book.
Also, since it is a place to store books that will be stored for a long time or a variety of books, it can easily get dirty if not cleaned regularly.

Let's take a look at what the interface specifically has as a structure.
The inside of the interface looks a little unusual.
There are no { }, which we usually see, and no access specifiers are visible.
{ } is called the implementation part, or body, because interfaces can only use methods without bodies.
So why does this code exist?

The interface is meant to provide a framework.
It's like saying, "When using the cleaning interface, you have to sweep, wipe, and arrange."
Additionally, the user can take the interface and implement it to suit his or her own taste.
As I showed you earlier, even though they inherited the same interface, the cashier mainly cleaned the counter, and the barista cleaned the coffee-related areas.

What happens when we click the time button? When we click the button, a screen appears showing the next hour, minute, and second.
So, the button has the function of 'moving to the next screen and showing information when the user clicks on it.'
It is not something that is static, but rather something that is implemented with dynamic functions.
Here, we will divide it into static, which is what is simply displayed, and dynamic, which provides the user with the desired function when clicked.
You can think of web publishers as creating static things.

If you're a large company, chances are you have a web publisher.
The work that web front-end developers do can vary depending on whether or not there is a web publisher. In companies with a web publisher, web front-end developers only develop dynamic areas, excluding static areas.
However, in a company without a web publisher, a web front-end developer can be considered to develop both static and dynamic areas.

The difficulty level is high as it contains 20 subjective questions within a large volume of material.
There are also programming language and SQL questions, and the difficulty level of these questions is very different between objective and subjective questions.
This is because you need to have memorized query statements to some extent and know the structure of a programming language to be able to write subjectively.

I had already been thinking about taking the civil service exam when I first enrolled in the government-funded academy.
Because I've heard a lot that it gives you extra points when getting a job.
In fact, you can find articles on job-specialized websites like 'Job Korea' that state the requirements for 'information processing engineers'.

However, since the written and practical exams are in the form of solving problems on a test paper, companies do not think that 'this applicant is good at coding' just because he or she has passed the information processing engineer exam.
I just recognize that the applicant has an IT engineer qualification.
However, since there are some areas where it is definitely recognized, such as public corporations, it is a good idea to acquire it if you have the opportunity.

Have you heard of the pufferfish technique before? It's a method I developed myself.
The Gaebokchi technique tells us to 'think big even in small things'.
The puffer fish is a fish that reacts very sensitively to even the smallest events.
Let's apply it to our self-introduction.
It's like the saying, 'Think big even about small things.'
For example, let's say the interviewer asks, "What is the biggest challenge you've faced in your life?"
At this time, surprisingly, there are quite a few people who think, ‘I don’t think I’ve ever experienced any great hardship in my life…’

What is hardship? Is it only life's hardships like recruiting a team of 50 people, starting a startup, and failing? Or is it only hardships like being suddenly scammed and losing all your savings? No.
'Studying development for six months as a non-major' can be difficult, and 'the team's situation was not good during a team project' can also be difficult.
The important thing is to show that you recognized each situation as difficult and what you did to overcome it.

Have you heard of a website called GitHub? It's where developers share code and even ask for help and solutions when they encounter problems.
You could say that this is a place where you can get a glimpse of the 'collective intelligence' of developers.
In particular, GitHub's representative service is a space called Repository.
When you post your program code, other developers can view and use it.
You can create your own portfolio right here.
Simply upload all your code to GitHub and attach a link to it to your application. You can also use the README to link to your code, making it easier to find, like a bookmark.

In this article, I will talk about how to upload code to GitHub using VS Code, one of the IDEs.
First, you need to install Git (source management tool) to be able to upload code to GitHub.
So, download Git first and follow along.
