Types of NoSQL Database and examples of NoSQL database.

What is NoSQL Database?

NoSQL Database is also known as  ” Not only SQL “, is a non-tabular database system, unlike a relational database. NoSQL provides a flexible, scalable, and high-performance database to the users. They are majorly used for real-time web applications and big data.

Traditional RDBMS uses SQL syntax for storage and retrieval of data, while NoSQL is ideally used for storing structured, semi-structured, unstructured, and polymorphic data.

When working with a massive amount of data, the response time for RDBMS is slow while NoSQL can be used for a large amount of data.

What is AngularJS?

AngularJS is a front end framework for single page applications. AngularJS is one of the most secure Javascript frameworks among other frameworks and it also has a strong support as it is managed by developers of Google. 

Currently over million of websites are made using AngularJS for their front end. According to me angularjs is going to be the best javascript framework for front end development. It is written in JavaScript. 

AngularJS Directives:

The AngularJS framework is majorly divided into three parts:

ng-app : This directive links AngularJS application to HTML.

ng-model : The ng-model binds the values of AngularJS application to the input controls of HTML.

ng-bind : This directive binds the AngularJS application data to HTML tags.

Top Programming Languages in 2020

Here is the list of the Best Programming languages of 2020.




      JavaScript is a text-based programming language that is used by Web browsers to create a dynamic and interactive user interface(UI). It can be used both on the client-side and server-side. In most cases, we use JavaScript for client-side scripting which allows your code to run on the browser, and JavaScript is based on ECMAScript specification.JavaScript is a dynamically typed language with many built-in functions.
It is a high-level language with curly-brackets syntax and just-in-time compiled programming language. Major companies use JavaScript including Google, Facebook, Uber, etc.
JavaScript has several frameworks, some of them are ReactJS, AngularJS, VueJS, ExpressJS, EmberJS, NodeJS, ThreeJS, BabylonJS.Basically, javascript frameworks are collections of javascript code that provides developers pre-written codes for creating web applications.

Three.js 3D JavaScript Library – Github

Three.js is an open-source, lightweight cross-browser JavaScript Library and API (application programming interface) that supports Canvas, SVG, CSS3D, and WebGL renderers and is used to create 3D animated computer graphics using WebGL.
WebGL(Web Graphics Library) is a JavaScript API that allows web browsers to render 2D, 3D graphics without installing any extra plugins or third-party plugins. Threejs simplifies the WebGL API.
It was released by Ricardo Cabello in April 2010, and the recent stable version of which came in March 2020. Three.js was previously written in ActionScript then ported to JavaScript language. The source code of this library is hosted in a repo on GITHUB                                       


 So here is the list of the best frameworks you can easily get started with and is going to be the future of web applications.

1. Angular

         The 1st place in our list of Best JavaScript Frameworks goes to Angular. Angular is the best front end framework used for making single-page applications.
These single-page applications are made using simple HTML and TypeScript. Today Angular is used for developing large-scale projects in big companies.
Angular is one of the most secure JavaScript frameworks used for developing applications. Currently millions of websites are using Angular including Microsoft, IBM, and Google.
Component-Based Architecture in Angular saves you a lot of time and also provides consistency for larger applications.
According to me, Angular is the best framework for the future of Enterprise-Scale Applications.

What is React JS? | Difference between ReactJS and React Native

React is an open-source javascript framework used to build responsive web designs. It is maintained officially by Facebook. React can be used as a base in the development of mobile websites or single pages applications.
If you want to implement React you should have a basic knowledge of HTML and JAVASCRIPT. React elements are displayed using the render() method.
React is a Javascript library that helps developers to design the best UI(User Interface) designs. It provides the best rendering performance and allows users to divide their complex applications into simpler components.

Some of the key features of React are:

JSX : JSX is an Javascript syntax extension.Most of the developers use this for React development.
