React was first released on May 29, 2013, and is now the most popular library for front end web development. But how did it become so popular and why do so many developers today use it on such a regular basis? In the following peace of line I will share with you 4 reason that makes attached to this Facebook Child
1-Virtual DOM
Working with Vanilla Javascript was cool , but one point that I have been always critisizing is the refesh page that we see while navigating in the webiste
First , let me tell you a little bit about DOM (Document Object Model) , you can think of it as a place wehere all the object of a web page are stored in a tree-like structure
JavaScript have to reload all the Real DOM , so he can update one elemenet of it , that's why you have to load your page to see that you profile name is Succefully changed in the website , until the React comes in
Now, you can Imagine Virtual DOM like a copy of the DOM ,but the virtual DOM doesn’t actually change anything that you see on the screen which is why it’s so fast. Essentially, the virtual DOM is like taking a screenshot of the real DOM and then saving it later.
Once the virtual DOM updates, it compares the updated version with a previous version of the virtual DOM. React then compares both versions of the virtual DOM to see what has changed through a process known as diffing and only applies those changes to the real DOM.
2-JSX
Jsx (JavaScript Xml) is a unifide syntax that makes web development much easier , becasuse it actuality combine Regular HTML and Javascript and put them both in same package
As you can see , "hello Jhon Doe" is what will be displayed on page , with jsx you can write function write logical script , use while , for loop , if else .....
You’ll notice that we still use camel case when using JSX, this is because JSX is still more similar to JavaScript than
it is to HTML
you can learn more about Jsx in React officiall documentaion React officiall documentaion

3-React is a Library
Over the past few years, React has exploded in popularity and is now the #1 JavaScript library out there today. Take a look at how React stacks up against other libraries and frameworks that are also popular
As you can see, there’s basically nobody who hasn’t heard of React and only a small percentage of those don’t have an interest in it or wouldn’t use it again. React’s popularity comes from its speed (Virtual DOM), reusable components, easy learning curve, and its developer tools and support. This also means that if you’re looking for employment, React is going to be your best choice when it comes to other libraries and frameworks out there
5-Mobile Apps With React Native
Although it’s not exactly the same as React, React Native allows you to create mobile apps for both Android and IOS. The syntax isn’t exactly the same as regular React, however, React Native is still extremely similar and won’t take you long to learn if you’re already familiar with React or even just plain JavaScript. If you don’t have a Mac and have an interest in creating mobile apps for IOS, then React Native is for you. React Native can also be used for developing for both IOS and Android simultaneously and is written with JavaScript and JSX just like regular React. React Native was released back in 2015 and is still somewhat new and has lots of room to be improved and expanded on
