Episode 11. Aren’t libraries and frameworks similar?

It's code that someone has written in advance, and it's a tool that makes our development faster.

In terms of 'who controls whom?', the difference between libraries is that the user makes all decisions and must follow set rules to use the framework.

Libraries: jQuery, Bootstrap, etc.

Framework: Django, Spring, etc.

React is described on the official site as a library. However, since it requires coding according to rules, it can also be called a framework, but as it is listed on the official site, it seems more correct to view it as a library.

Episode 12. Is jQuery a must-learn skill?

The popularity of jQuery, which appeared at a time when JavaScript was not compatible and the code was not clean, could not help but rise. Nowadays JavaScript has improved functionality and is easier to write code, so there is no need to learn JQuery.

When I first started learning, I think I briefly learned JavaScript and then moved on to learning JQuery. In practice, I have seen many people who prefer jQuery for its clean code, but now that they use JavaScript more cleanly, they are forgetting the need for jQuery.

Episode 13. What on earth is that damn API?

Just like you use a keyboard to communicate with a computer, an API is a type of coded rule that programs use to communicate with each other.

Abbreviation for Application Programming Interface.

API is a pre-made function that is used when you want to get the desired result, so you cannot know the function of the API. Try developing the API yourself or use the functions you need depending on your needs.

Common mistakes beginners in programming make

Trying too hard at first.

• It is a good idea to change it into a habit that you continue to do every day. Proper distribution of daily work and time is required!

I study only to check whether I have studied.

• Rather than studying a program by checking a TO-DO list as if you were working, it is more efficient to focus on what to create and study. You can also create a job portfolio, so you kill two birds with one stone!

Study without a deadline.

• If you study on your own, set a separate deadline for your studies.
• If you don't set a deadline, it's easy to let time pass by helplessly.

All of these mistakes are mistakes that we have experienced and perhaps even make today. In my case, I think it is effective because I plan a project in advance and decide on new technologies to try. I need to learn the technologies quickly so I can build them into the project. On the other hand, TO-DO writing is not scheduled on a daily basis, but divided into monthly and weekly schedules. It is convenient to do it while managing the Kanban board, as it allows you to see the progress of work. Still, it is not always an easy task to create and achieve a schedule that satisfies 100% satisfaction.

Episode 14. Why should you pay for a domain?

You can think of it as a phone book that manages phone numbers.

When I first got web hosting, I was surprised to learn that domains were quite expensive. Of course, the price is low considering server and cloud costs, but I thought it would be cheaper.

There is a way to manage a domain system, which is to use the registry. The representative registry called .com is managed by a company called VeriSign. Domain sellers must use other resellers. Reseller companies sell domains at a slightly higher price than the actual cost because they handle domain management and membership management.

You can request ICANN to operate a domain registry, but it costs about 220 million won. And you have to prove that you have operational capabilities.

• The registry is what creates the domain.
• The registry is a phone book that contains IP addresses and domains.
• Becoming a registry operator requires a huge amount of money and infrastructure.
• When you purchase a domain, you are paying a reseller, not a registry operator.
• Resellers do things like manage contracts, process payments, and pay domain fees.

Episode 15. The End of Flash and Steve Jobs

Flash was a product for people who drew comics and animation. After acquiring Macromedia, the program name was changed to Flash, allowing animations to be displayed in the browser using the Flash Player plug-in.

Why Steve Jobs opposed the use of Flash

• Flash is not open source
• Flash is unreliable.

Flash was again acquired by Adobe. Steve Jobs, who was thinking about free web standards at the time, thought it was unacceptable for one company to control everything and make decisions. Flash made iOS development for touch difficult. And eventually, it was possible to create a website without Flash.

This was a part where you could feel how great Steve Jobs' power and action force was at the time. What I am truly grateful for now is that, with a certain thought, I went beyond business and created a change that led to web standards around the world.
