Hello. I'm a college student majoring in web development.
My academic classes are almost over. Now, I'm preparing to job hunting to become a front-end developer such as resume, portfolio, LinkedIn so on and so forth.
If you are interested in my portfolio, here is the link. https://shihokazama-portfolio-miacan2021.vercel.app/

Today, I'll share my experience of how I learned React. Hopefully, It will be helpful to someone who is a beginner at coding and struggling to understand React.

Where did I start from learning?

I entered my college in Apr 2021.
I've already understood HTML and CSS and basic Javascript until June.
As for "basic Javascript", I could handle DOM; apply a new class name by event listener and then fire animation etc.
I put the link to the Landing page I created in June. It's also mobile-friendly. I made it for one week or so.

I started studying React in June but It didn't work. I couldn't understand React at all, even after watching several tutorials and googling "React for beginners" lots of times.
How come? I analyzed the reasons.

I've been neglecting my Javascript studies.

Some web developers said you don't need to study Javascript a lot, we don't use Javascript. We use React. So, you have to study React, not Javascript.
That's true! Most of the companies don't use only Vanilla JS, they mainly use React, Vue, Angular etc.
However, I think web developers shouldn't say that to beginners like me! Now I see there is a big difference between developers and beginners about the level "Don't need to study Javascript so much".
When I thought I've already had enough knowledge of Javascript, it was time to start learning React!, but I was at the level just understood about DOM manipulations.
I didn't have knowledge of how to handle arrays and objects, what is class, and when I needs to write asynchronous functions.
Believe it or not, I didn't know the difference between "map" and "forEach".
I highly recommend that you take longer than you think is enough to understand Javascript before starting to study React for beginners.
React is a JavaScript library.
Don't neglect to study Javascript, or you'll get stuck in your React studies.

Finally, I could create an EC website from scratch in vanilla Javascript.

I wrote the whole code (add cart, delete cart, shop items are in class etc...) in Javascript. I didn't copy others' code at all, I thought myself how I operate it in Javascript. I was sure I have a solid knowledge of vanilla JS at last!

Restart learning React

I restarted my React learning in September. I could understand it easily!!!

I created my first React project in September it was a chatbot.

And I made a weather app using API in September.

I wrote an article about React Hooks in December.

And then, I created React Redux project in December.

I'm sure I'm growing as a front-end developer very fast.
Now, I'm searching for a job!

Through this process, I think I have escaped from being a complete programming beginner. I learned that understanding a programming language takes a certain amount of time and that it is important to build up a solid knowledge base.
Thank you.
