**First Project Retrospect**

Our final project ended today.

It turned out really well. I honestly thing that our group’s project was one of the best. All thanks to my awesome teammates.

This project took 4 weeks to complete.

The name of our project is : “Yeongn Market”(‘yeongn’ is a lotus flower root).

It’s basically an website where you can get appraisal of the item you have and sell it.

Here’s the link of our website : https://www.yeongn.com

Everyone did a great job to make things work and look nice too.

Today I studied inheritance patterns with my pair.
The name of the sprint was ‘BeesBeesBees’. We had to solve the problems in two ways.

Planning to study more about CSS. Probably going to check out w3schools.
Hopefully, I learn a lot tomorrow.

OOP stands for Object-Oriented Programming(객체 지향 프로그래밍).
Originally, the computer was using Procedural Programming.
It’s about telling the computer what to do step by step. Procedural programming relies on procedures. However, as time goes by it wasn’t really easy for procedural programming to catch up with our big, developed projects.
