Angular also referred to as 'Angular2' or 'Angular2+'. It is an open source Single Page Application (SPA) based on TypeScript, completely client-side framework. Angular is a product of Google. Furthermore, TypeScript is an open source programming language, produced by Microsoft. A SPA is a website that dynamically responds to the user without reloading the entire page from the server. In a SPA, all the required HTML, JS, and CSS code is retrieved with a single page load. JavaScript is much faster than having to contact a server for every page change and for every new piece of data to display. Therefore, this approach allows us to create web applications that look like mobile applications, very quickly. Yes, if some data is needed from the server, it does the work in the background, so that the user does not always lose the image of the responsive web application. It works by modifying the DOM of the HTML by JS at runtime. Say no to plagiarism. Get a tailor-made essay on "Why Violent Video Games Shouldn't Be Banned"?

To use Angular you need knowledge of HTML and CSS. Angular combines declarative models, dependency injection, end-to-end tooling, and built-in best practices to solve development challenges where it enables developers to build applications that live on the web, mobile, or desktop. Since CSS is a style sheet, it defines the way of presentation, such as layout, colors, HTML fonts. A single CSS file can be included or shared in many HTML files to be displayed with the same perspective or specify which element should be shown as similar. Therefore, it saves a lot of time, reduces the reproduction of additional code and increases production. The World Wide Web Consortium (W3C) is a maintainer of the CSS specification. JS is a scripting language. VanilaJS means without JS libraries. Besides HTML and CSS, JS is one of the main technologies of the Web. JS is the third layer of standard web technologies. Since the entire modern web supports JS and the growing job market, every web developer should learn JS nowadays. In fact, currently without knowledge of JS you cannot be a web developer. NodeJS is an open source JS-based framework for the server side. It supported cross-platform and was based on Chrome's V8 JS engine which uses a non-blocking, event-driven I/O model. So, it is lightweight, efficient and since it is JS based, the popularity of NodeJS is increasing nowadays. NPM packages help to install all Node libraries easily, they are open source. MongoDB is one of the most popular NoSQL databases in the academic and business sectors. It is one of the most commonly used NoSQL databases widely used in Node. js. MongoDB is an open source database that provides a data structure of pairs of fields and values ​​and provides automatic scaling, including high performance and high availability. MongoDB documents are like JSON objects. They are like JSON objects where documents, arrays, and arrays can have other documents in the field values. In many programming languages, MongoDB document targets are native data types. Additionally, costume combinations and arrays are reduced. Due to the dynamic nature of MongoDB, it is compatible with polymorphism flow. Since it provides high data consistency, it supports integrated data models, which reduces the effort of.
