What is Node?

 It is a runtime of JavaScript; meaning it is a way of running JavaScript outside the browser. Now, it's not the JavaScript that front-end developers are used to because there is no longer a browser to work with. But all JavaScript's core parts remain: arrays, objects, loops, conditionals, architecture asynchronous, etc. This means that if you are able to write JavaScript in the browser, you just need to let go of the browser and write code for anything. Just like PHP, ASP, etc.

What are the advantages of learning Node?
  • You don't have to learn a new language to use Node once you've learned JavaScript, and you can use it throughout the stack.
  • Unlike all other languages, you can write JavaScript from start to finish and even accept JSON natively.
  • It works especially well whenever you receive a lot of requests because JavaScript is asynchronous.
  • It's incredibly fast when it comes to traffic handling, and it has any language's largest module market. NPM (node package manager) has grown at a meteoric rate and there are multiple modules of just about everything.
What are the disadvantages of Node?


  • It takes quite a bit of knowledge to write a web server in Node.
  • Compared to most entry-level languages, it is quite a young technology, which means that there are not as many starting resources as they have not yet been developed.
  • The greatest strength of JavaScript is the fact that it is asynchronous, but it is a primary complaint as well.
  • Confusion, the hysteria of callback, and frustration are common as JavaScript is not running from left to right and from top to bottom.
  • It is not ideal for CPU-heavy applications.
  • If you're going to have a chance, you'll need to embrace promises–something no other languages need to worry about.

Spring Boot is a way to bootstrap any Spring application or create it quickly. Here's Spring Boot's official definition. Spring Boot makes it easy to create stand-alone, production-grade Spring based Applications that you can "just run". Spring Boot helps you to quickly create any Spring application. It provides default configurations that help you avoid a lot of hard-to-maintain boilerplate code. Advantages of Spring Boot It provides many default configurations to help you create the Spring application more quickly. It comes with a tomcat or jetty server embedded, so you don't have to deploy jar. By avoiding a lot of boilerplate code, it reduces development code. As you can quickly create a Spring application, it increases productivity. It provides plenty of starting project for easy integration. You don't have to worry about the mismatch version.

An Introduction to JavaScript

JavaScript is a powerful programming language that is used at the front of most of the websites that you access. It makes an interactive website and adds functionality, creating a user experience that is much more satisfying. When you click on a button on a website or see something moving, there is a good chance that JavaScript has been used to make this happen. JavaScript is more of a programming language as it uses traditional coding concepts such as variables and functions to improve the language's performance. Although learning is more difficult, JavaScript is a necessity to explore as it adds so much more to a website than just HTML and CSS static output. You may think of HTML as the site's structure, the look and feel CSS, and JavaScript as a website's functionality and interactivity. On the front end of a website, all three are used, but for different purposes. There is a wide range of enhancements that JavaScript can accomplish. Creating buttons and response...
