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.

@owenmurphy2022 9 месяцев назад

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.

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

@arunvishwakarma2779 3 года назад

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 2 года назад

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 2 года назад

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

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

@hardikpoudel3011 2 года назад

what is the difference between transpiled and compiled

@PortEXE 2 года назад

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.

@abdelaesus6678 3 года назад

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 3 года назад

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 3 года назад

@@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 3 года назад

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.

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?
