JSX is build with two things JavaScript + HTML. Which mean React understand JSX, and JSX is only for react. React doesn’t understand the HTML, React only understand JSX but we can write HTML under JSX, JSX is built like the HTML, When you will write the code you will not fill much difference between HTML and JSX.

Don’t be panic think JSX is just an HTML, but it’s not an HTML this is actually JSX, But it look similar to HTML.

What is Components in React ?

This is the second feature of React JS after the JSX, And this is also an important feature of react. If you guys studied angular before, You can feel what is power of components in react. Yes Component is very powerful feature of react with some unique power.

If you are worrier about you don’t know what is component and it’s use. I will let you every answer of your question.

Just take it in a simple language, Components is just like a container of a web page. A website is a made of different components like header, footer, and body. Like in HTML we have to write the header code in every page of website, But the technology is getting advanced. We can use the components.

We don’t have to code the same thing in each and every page, just import the component of the code which you want to display on the page. And this is very simple and useful.

So what does this term mean, This mean a data coming from one source to destination. When the data coming from source to destination it mean data are getting bind. And this is only in one way transfer of data from source to destination. This mean One way data binding.

Where all parents can send the data to there children, and there is also an option of taking response from children. But the package of data, the path of data and the transfer of data are in one way not in two way. But there is a way where children can communicate with parents, We will know this further of this post.

What is Virtual DOM in React ?

So what does virtual DOM mean?, You heared a DOM word many time but what virtual DOM mean. If you study javascript before then you should know about what does DOM mean. But if you don’t know no worries i will explain you what does it mean.

If you are going towards react at lest you should know the basic of javascript. We have seen the DOM in javaScript which stands for Document Object Model(DOM). And if you learned the jQuery before there is also a term called DOM.

But in the react this is not an actual DOM this is a Virtual DOM. If you guys are thinking what is a difference between virtual and actual DOM. To understand the difference between this two, We should know about what is DOM rendering.

How React do a DOM Rendering ?

This is also an important things to understand to know more about react, And it plays the important role to creating a website with React JS. But what does actually DOM rendering mean, In the above paragraph i said there are two type of DOM. Let’s understand both of them before knowing about DOM rendering.

Actual DOM:- If you guys know the basic of javascript then you hared the DOM word many time. Which means document.getElementById (DOM). The function document.getElementById is used to pick a DOM element.

Virtual DOM:- As in the actual DOM we are using document.getElementById, To pick a DOM element. But in virtual DOM we don’t have to use the document.getElementById. Before the actual DOM render on website there is copy made of the Actual DOM which is known as virtual DOM.

And this DOM knows in which part which element is written. Let’s take an example when the user will click on button and one DOM element get’s change. But the first change will made in virtual DOM compare to Actual DOM.

This is a one more reason why everyone love react as a frontend. Because if there will be a change made in element then the not all DOM will be render as a actual DOM. But only the element will be rendered where the change happen.

So this is how DOM rendering work, And how this play a important role to make react as a great frontend library.
