Node.js is a server side platform built on Google Chrome's JavaScript Engine (V8 Engine). Node.js was developed by Ryan Dahl in 2009. The definition of the Node.js as supplied by the official Node.js documentation is as follows - " Node.js is a platform built on Chrome's JavaScript runtime  for easily building fast and scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices. " Node.js is open source, cross platform runtime environment for developing server-side applications. Node.js applications are written in JavaScript. Because of the arrival of Node.js, way of the web developing was completely changed. Early days, most of web applications had used PHP for their server-side. Therefore, one must know javascript and php for become a full stack developer. Now, front-end developer do not need to know other serv...

Today we are gonna talk about JavaScript, Version controlling and NoSQL. In JavaScript (js), we are going to know what is js, classes, objects and prototypes, how 'this' key works, strict notation, function closure, callbacks and promises. When it comes to Version controlling, we are gonna talk about what and why? terminology, best practices and GIT. Latter part, we are gonna learn about what is NoSQL, pros and cons and MongoDB. JavaScript JavaScript is a scripting or programming language that allows you to implement complex features on web pages. Web pages are not the only place where JavaScript is used. Many desktop and server programs use JavaScript. Node.js is the best known. JavaScript was invented by Brendan Eich in 1995, and became an ECMA standard in 1997. ECMA-262 is the official name of the standard. ECMAScript is the official name of the language. ECMAScript is often abbreviated to ES. ES5 and ES6 are the most widely using versions. ES9 was released in 2...

Welcome everyone, this blog is about to provide in depth of Mern Stack technologies. Before we jump into the main topic directly, we should have a solid background about Application Frameworks. This post is here to give you that. First of all, we have to figure out what is a  Application Framework? An Application Framework is a platform to build software applications. It acts as a skeleton to support development of applications. Adhering to the terms and guidance that provided by the team of developers who has developed the framework, we can develop software applications conveniently. Three principles of Application Framework, 1. S.O.L.I.D 2. Approaching the solution 3. Implementing the solution 1. S.O.L.I.D S - Single responsibility principle; A class should have one and only one reason to change, meaning that a class should have only one job. If there are more jobs, you should create classes for each job. This way, you can develop software applications ea...
