Bite-Sized React (React.js): From Basics to Practice Course

Hello everyone, this is Lee Jeong-hwan 😀

Is there anyone who might be having concerns like the ones below?

"I want to work on a proper project, but... I'm not sure what topic I should choose"

"Design, backend, requirements gathering, and more... I want to focus only on frontend development, but there's too much to do"

I really want to work on a project, but...

For those who cannot take on various challenges and difficulties

We've prepared a collaboration event with PROKIT😀

What is PROKIT?

Project Kit for Those Who Dream of Becoming Professionals - PROKIT

PROKIT is a resource collection (kit) for frontend projects

Business scenarios, planning requirements, design mockups, backend servers, and other

It consists of various materials for conducting practical projects.

Focus solely on implementing frontend functionality

Who created PROKIT?

This is a project created by my benefactor, who was with me at the beginning of the One Bite series.

PROKIT guided me to take my first steps as an instructor,

who helped make the current One Bite series possible

This is a new project planned by Ko Young-jae, CEO of NYBS.

Youngjae Ko has been planning IT education content and curricula for a long time

This is someone who has helped create the beginnings of countless instructors.

I also spent a long time with Youngjae Ko while preparing the One Bite series,

In that process, we naturally came to share similar philosophies and directions.

I believe you will also be able to feel the sincerity and depth through PROKIT.

Half of it is my heart cheering for Youngjae's new beginning,

And with the expectation that it could be helpful to all of you

We have prepared this collaboration.
