-

                                                                 
                                  JavaScript

JavaScript is an interpreted programming language. It follows the ECMA Script specifications.
JS allows to create interactive web applications and web sites using its pure functionalities,libraries and frameworks.

Js is  lightweight and dynamic.It allows allow client-side script to interact with the user and make dynamic pages with some object oriented capabilities!

                                                           Is JavaScript Object Oriented?
JavaScript is object-oriented, but is not a class-based object-oriented programming language, it is a object based programming language.It can support OOP because supports inheritance through prototyping also properties and methods. You can have polymorphism, encapsulation and many sub-classing paradigms
                                                              Java vs JavaScript
`When JavaScript was created, it initially had another name: “LiveScript”. But Java was very popular at that time, so it was decided that positioning a new language as a “younger brother” of Java would help.
But as it evolved, JavaScript became a fully independent language with its own specification called ECMAScript, and now it has no relation to Java at all.`

>>>>>> Usage of JavaScript
  • Web development
  • Web Applications
  • Presentation
  • Server Application
  • Games
  • Web Server 
  • Art
  • Smart watch applications
  • Mobile applications
  • Flying Robots


>>>>>> Advantages of JavaScript
  • Less server interaction − You can validate user input before sending the page off to the server. This saves server traffic, which means less load on your server.
  • Immediate feedback to the visitors − They don't have to wait for a page reload to see if they have forgotten to enter something.
  • Increased interactivity − You can create interfaces that react when the user hovers over them with a mouse or activates them via the keyboard.
  • Richer interfaces − You can use JavaScript to include such items as drag-and-drop components and sliders to give a Rich Interface to your site visitors.

>>>>>> Limitations of JavaScript
·         It does not have any multi-threading or multi-processor capabilities( JS is synchronous programming language)
·         Does not allow the reading or writing files

ReactJS React is a front-end library developed b y Facebook. ReactJS presents graceful solutions to some of front-end programming’s most persistent issues.  It is used for handling the view layer for web and mobile apps.   It’s fast, scalable, flexible, powerful, and has a robust developer community that’s rapidly growing. ReactJS allows us to create reusable UI components. It is currently one of the most popular JavaScript libraries  According to React official documentation, the following is the definition − ` React is a library for building composable user interfaces. It encourages the creation of reusable UI components, which present data that changes over time. Lots of people use React as the V in MVC. React abstracts away the DOM from you, offering a simpler programming model and better performance. React can also render on the server using Node, and it can power native apps using React Native. React implements one-way reactive data flow, which reduc...
