                   Babel is the most popular transpiler for javascript.This is an open source transpiler. Now a days ES6+ (ECMA Script) is the javascript version. Some browsers still can read old javascript versions only. Eg:- Internet Explorer. If we used latest version of javascript for the program that might not executable in those older version browsers.                    In order to solve that this Babel transpiler convert Latest version javascript in to old javascript version, Some companies use Babel Instagram Discord Yahoo GitLab Conversion Example Arrow Function in to javascript function                 //Latest Version CalculateValues = (x,z) =>{ const sumIs = x+z; return sumIs; } //After Transpiling function CalculateValues(x,z){ var sumIs = x+z; return sumIs; ...

What is React                   React is a JavaScript Library use to develop User Interfaces.Using this library we can isolate complex user interface in to a isolated part called "Component", within this component we can manage interface. What's are the differences between state and props ?                   Props                      "Props" is a shorten form word in order to describe properties.These properties are useful when we are going to transfer data among one component to another component. This transaction should be done form Parent component to Child component only, This is a noticeable feature in react called "one-way data flow" and also these props are immutable.                   States                       Th...

What is NodeJS ?                    Actually this is the runtime environment for the JavaScript, This runtime environment built on Google Chrome's V8 engine.This also an opensource, which is used to implement Server Side Scripting.The foundation of this language is based on C++,C,JavaScript. Because of the cross platform usage NodeJS is famous among developers. There are several NodeJS Versions which are launched before, But now a days V13.8.0 is the latest updated version.                    Commonly known as a lightweight environment, Because in java there are several threads which are running background, But when we are considering this there are no any Multi Threading concept.But there is an event loop in order to done process.                     That's what made this lightweight.

What is this Database ?                       NoSQL also known as the Non-relational or Distributed Databases. This was introduced by Carlo Strozzi in 1998, As describe in this name there are no any sql included to this NoSQL. So.. you wonder, then how are we suppose to store data without SQL.                       we don't  need tables to store data in this databases. But there are four basic types in this database.Those four basic types allows to handle huge data and manage the traffic of it. Four basic types are, Column-Based Store  :- HBase , Cassandra Key-Value Store  :-   Riak ,  Amazon S3 Document-Based Store  :-  CouchDB ,  MarkLogic Graph-Based Store  :-  Neo4J This databases are mostly used in industry,Because there have so many advanced data handling capacity and capability of huge...
