What is React?
In plain English,React is considered to be the View 'V' in the Model View Controller (MVC) model.Views are the logic-less files that are controlled by a 'Controller'.React does not replace the view,rather it makes it more modular by creating highly reusable components(pop up modals,lists,sortable tables, etc)..
The enormous thought behind React is making your own components like HTML elements.In React,a page is an accumulation of littler pieces,these little pieces are called parts.Developers can utilise these components to efficiently create large web applications,which can change the displayed elements or data without the need to reload the page.a simple example of this would be Facebook likes.The number of likes can increase or decrease without having to reload the page.This method has made it very easy to build modern,complex user interfaces.
Evolution of React
In 2011,Facebook developers started to face some issues with code maintenance.As the Facebook Ads app started growing exponentially,the team needed more people to keep it running perfectly.over time,their app became difficult to handle,as they faced a lot of updates.Their code demanded an urgent upgrade to become more efficient.
They had the model right,but they expected to take care of client experience.Jordan Walke,a programming engineer at Facebook,built an underlying model that mode the procedure more systematic,and this is when React.js appeared.

Important features of React JSX
ReactJS Institute in Bangalore JSX is basically a syntax extension of javascript which describes what our UI should look like.It is versatile,allowing you to put any javascript expression inside of the curly braces.It can be a logical expression like (2+9),calling a function or accessing objects.Once compiled,these JSX articulations become javascript capacity calls which return javascript objects.JSX can likewise be utilized inside circle and contingent explanations.The following is an example of JSX code :
Const person = {
f_Name : 'John',
l_Name : 'Doe',
function returnName (person) {
return person.f_Name + ' ' + person.l_Name;
const elementJSX =

Hello, {returnName (person)}!

ReactDOM.render (elementJSX, document.getElementById('root'));
In the above example,we embed the result of the Javascript function, returnName(person, into and element.
The consequence of this code is the accompanying :
Hello,John Doe!
Virtual DOM
Respond makes an in-memory information structure cache,which registers the progressions made and after that updates the program.This feature allows only those components which have been changed to be updated,rather than reloading the whole page.
Single way Data Flow
In React,it is not permissible for the components to edit any properties directly.Instead,they have to pass a callback function with the help of which properties can be modified. This information stream is also called "Single way Data Flow".
React Native
Respond has local libraries which Facebook declared in 2015.These local libraries give the engineering to local iOS and android applications.
