  • Top 5 JavaScript Framework in 2018



    Everyday new technologies are there in market .JavaScript frameworks in the top most framework for developing front end web application and also mobile application . Basically Technologies are in the race of speed of application . How Fast Website Executes .

    1. Angular JS- 

    AngularJS is a JavaScript-based open-source front-end web application framework mainly maintained by Google and by a community of individuals and corporations to address many of the challenges encountered in developing single-page applications .
    This is most of the popular framework for Front End Web Applications . 

    Features - 

    • Single Page Application
    • Progressive Web Application
    • Fast Web App
    2. React JS - 

     React is a JavaScript library for building user interfaces. It is maintained by Facebook, Instagram and a community of individual developers and corporations.React is very fast framework for website development and maintained by  Facebook .

    ReactJS is a component-based javascript library which is used for building an interactive and dynamic user interface for websites and mobile applications specifically for developing single page applications where data reflects in real time. Currently, it is one of the most popular front-end JavaScript library in the market. It deals with View in the MVC(Model - View - Controller).
    Features - 

    Declarative:
    React creates very interactive and dynamic user interface for websites and mobile applications. Create simple views for each state in your application, and React will efficiently update and render just the right components when your data changes. Declarative views make your code more readable and easier to debug.
    Virtual DOM
    In React, for every DOM object, there is a corresponding "virtual DOM object." A virtual DOM object is a representation of a DOM object, it creates a virtual copy of the original DOM. It's a one-way data binding hence manipulating the virtual DOM is quick rather than updating original DOM because nothing gets drawn onscreen.
    Event handling
    React creates its own event system which is fully compatible with W3C object model. All browser’native events are wrapped by instances of Synthetic Event. It provides a cross-browser interface to a native event. That means you do not need to worry about incompatible event names and fields. Besides, React event system is implemented through event delegation and also has a pool of event objects to reduce memory overhead.
    JSX
    JSX can best be thought of as a markup syntax that very closely resembles HTML.It is more or less like the combination of Javascript + XML. JSX makes writing React components, the building blocks of React UI, easier by making the syntax developers use for generating these strings of HTML almost identical to the HTML they will inject into the web page.JSX is one of best ReactJS features. Web developers will always go for an easy way out, which is why this is a great choice for many.
    Performance
    React uses one-way data binding with an application architecture called Flux controls.ReactJS helps us update the View for the user and, with Flux, can control the application workflow. Introducing virtual DOM adds advantages where it compares the new data with original DOM and automatically updates the view.
    React Native:
    React Native is a custom renderer for React, just like React DOM on The Web. React Native uses native components instead of web components like React as building blocks. To begin with React Native, you need to know the basic React concepts, like JSX, components, state, and props. If you know React, you still need to learn stuff specific to React Native, like the native components. React Native also gives access to the features these platforms offer, apart from transforming React code to work on iOS and Android.
    Component-Based
    In React everything is component the web page divided into small components to create a view(or UIs). Every part of applications visuals would be wrapped inside a self-contained module known as a component. Since component logic is written in JavaScript instead of templates, you can easily pass rich data through your app and keep the state out of the DOM.Components in ReactJS use to define the visuals and interactions in applications.
    Conclusion:
    Applications built on ReactJS uses new technology that has not been used before in web application development. It is a perfect tool to make high-performance presentation layer for your application. And it can be even faster if you take the advantage of immutable data structures. As ReactJS features like components allow you to develop new features in React without rewriting existing code.

    3. Node.JS - 

    Node.js® is a JavaScript runtime built on Chrome's V8 JavaScript engine. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient. Node.js' package ecosystem, npm, is the largest ecosystem of open source libraries in the world.

    Basically Node.js is very fast framework and used javaScript technology is very fast.


    4. Vue.js 

    Vue.js is an open-source JavaScript framework for building user interfaces. Integration into projects that use other JavaScript libraries is made easy with Vue because it is designed to be incrementally adoptable




    5. Ionic framework 

    Ionic is framework for developing Hybrid app development using web Technologies html , CSS ..
    Ionic uses angular as a programming language and Cordova plugins for access native functionality.

    Using Ionic framework you can develop Android , IOS, Windows and web applications.

    so this is very cool framework using JavaScript technology.
