I am self-taught programmer. I work now as a professional software developer in international corporation, but to those days I'm amazed how most of tutorial and article creators start they explanation from "How" not "Why". That's why videos like that literally make my day. Thank you for your work in the name of community.

[@PhalgunRangaraju]

Huge thank you. As someone who's coming back to frontend after a break this is a helpful video.

[@itsankk]

The best video I found after searching for 'How React works'. Very clear and simple to understand explanation. Thanks.

[@iancuvlad7368]

Extremely comprehensive explanation for webpack, you helped me a lot.

[@waseemmehmood5685]

The explanation was so simple and straight 🙌 well done man 🔥

[@nayeemahmed5169]

This is so nice demonstration. This helped me a lot to understand the whole thing. Thank you so much.

[@bushbuddyplatypus]

Very welcome info less that an hour before my job interview. Pitched just right and I feel I know a lot more more now. Thanks

[@philmyglass877]

Great vid and good explanation for something that is quite complicated for a newbie to understand!

[@vatsee]

Thanks for the work and for the explaining how it all ties together. Appreciate it!

[@JoeyLutes]

been writing JS all year and this helped solidify my mental model of this stack, particularly how React uses Babel to parse JSX

[@PortEXE]

Making the video helped me solidify my understanding as well

[@omarlyadini9765]

insane explanation, you are doing an amazing work, love it thank you

[@vishalsrane]

Most knowledgeable video I have ever seen on react. You are the best!!

[@simple8810]

This is very helpful video ,I am working on react from last 3 month but had no idea of how react work under the hood, So I learned here babel, webpack , node module, virtual DOM and browser DOM Thanks a lot man

[@coreyamccoy]

This is by far the best explanation of how React works from both a technical and application standpoint...👏🏼...👏🏼...👏🏼 (well deserved slow clap)

[@redori]

Really great video man. I think video could be a bit better if mic isn’t covering your face, idk why but it seemed odd to me

[@akashshrestha01]

great

[@JakeJJKs]

If you look closely in this video, you can see that there's actually a person behind the microphone. This person is likely the narrator in this tutorial.

[@owenmurphy2022]

This video is great for beginners but I was looking for something that explains react as its core and the design followed, and the component lifecycle. It seems you talked mostly about Javascript and the tools that react uses as the most basic level which occupied most of the video.

[@tatyanatarasova6480]

Thank you! would be much better if you put more pictures, diagrams, texts of what you are talking about. thank you agian.

[@yanfengliu]

Nice video! Could you please remove the vignetting effect though? It makes part of the code really hard to see

[@aaronalquiza9680]

as a web developer for 7 years, i already understood how most of it works, and was expecting explanations on the Diffing algorithm itself. but this is very good content for web developers just getting into React.

[@commondev2595]

Same i am looking for how Diffing actually works. Did u find a good place to read/watch ?

[@fbiindia9661]

Let us know if you find that

[@vivekkumar36732]

Fantastic 😍😍

[@uguryl]

👍💯

[@sivlongtaing]

I have a question? Will you be able to show us on how to react a regular website. I created a website. Now, I would like to create a react website version of it. Thanks for the explanation.

[@PortEXE]

Hey that’s an interesting idea! I may do that.

[@arunvishwakarma2779]

I literally loved the video, got most of my doubts cleared. However, I have one doubt, when I tried Babel in their official website, and tried to use Arrow function which is basically ES6, on the right hand side exact thing was there. I thought Babel converts to ES5 so I thought Arrow function will be converted to normal function

[@cocolasticot9027]

I think that's because our latest builds/versions support es6 already. You can remove everything in the "targets" field, it will be converted to es5.

[@simple8810]

I tested the same, it gives me the same function and I had read that babel will convert the arrow functions to regular function as in es5

[@liamconverse8950]

I was basically just wondering if the react hooks syntax was valid JavaScript or if that's just like JSX that has to get transpiled

[@abdulrahmantahir3033]

what explanation do you got ? i am also wondering about it and where should i know how exactly react works under the hood ?

[@LukeryaPereprygova]

Visual aspect note - it's kind of weird to see half of your face blocked by the mic and pop filter all the time. Maybe consider choosing a different angle

[@PortEXE]

I’m just going to get a massive pop filter so that all you can see is the pop filter 🤣

[@danielromeo99]

y dark screen??? but great video

[@hardikpoudel3011]

what is the difference between transpiled and compiled

[@PortEXE]

Transpilation basically converts one language into another. Compilation converts your code into a lower level machine-like code. These terms can be different depending on who you're asking too.

[@Andrew-hl7xq]

Great vid, less vignette m8. ;)

[@bakarandguladze]

[@cypher9000]

What's with the crazy vignette all over the place? Is it to make the code look artistic?

[@PortEXE]

It was an accident 😅

[@ikurbano]

Thank you! but, please loose the background music, it doesn't help with focusing on the material, which is great, btw, content-wise and delivery-wise.

[@vishalsaraganachari1604]

Nice content 👍 but dude you have to go little slower , it's very beneficial for non native English speakers.

[@baskaal]

"The rest is empty with no brain but the clever nerd"

[@DanKaschel]

I was hoping for less about tooling and a deeper dive into the mechanics of react, such that I could build an intuition about how react will behave.

[@abdelaesus6678]

I really don't understand how React can be anything other than a framework. It makes you think and organize your code in a specific way. If someone could explain to me, I'd be interested.

[@PortEXE]

The React ecosystem as a whole could be thought of as a framework, however React itself is simply a JavaScript library that you import and use as you please.

[@abdelaesus6678]

@@PortEXE Ok, I understand. Because what people refer to as React is actually React + react-dom. So react is a library, but coupled with React-dom or React-native, it becomes as framework. Is that it?

[@PortEXE]

Well react-dom is also just a library, it’s when you start to think of React as React/ReactDOM, Babel, Webpack, React Scripts JSX, etc that it looks more like a framework. But in reality these are all completely different tools that exist separately from each other.

[@abdelaesus6678]

@@PortEXE ok, I see. I thought JSX was a feature from the React library

Great explanation, but could you please remove the side shadows at least when you're showing the code? it's annoying.

[@Xiler6969]

Really underrated video and channel. Your core is there, just need a bit better editing, need to shave your stash and you need better thumbnails. I wouldn't be surprised if you start getting 10-30k views soon.

[@Xiler6969]

@@PortEXE Don't let pride inhibit your potential.

[@i-am-the-slime]

I was disappointed by this video. I was hoping for an explanation of how React works. What happens when I register a hook, is it there a lifecycle, how does it diff the VDOM etc? Does anybody have a suggestion on a video that explains that?
