What is JavaScript and what is it for?

JavaScript® (JS) is a lightweight, interpreted, or compiled, object-oriented language with first-class features. It is most widely used as a scripting language for web pages, web documents, and web applications, but is also used in other software products, for example, Express.js, Angular.JS, Node.js, etc.

JavaScript is commonly used as an embedded language for programmatically accessing application objects. It is most widely used in browsers as a scripting language to add interactivity to web pages.

The main architectural features of the JavaScript language:

  • dynamic typing,
  • weak typing,
  • automatic memory management,
  • prototype programming,
  • functions as first-class objects.

JavaScript has been influenced by many programming languages, to make the language similar to Java, but easier to use for novice web programmers.

JavaScript as a modern programming language

Today JavaScript is not just a change of a web page depending on the actions performed by a visitor, but a universal web programming language for creating web applications, server, desktop, and mobile applications.

Previously, its application ended with a web browser, and today JavaScript allows you to create:

  • Client-side of web projects
  • Server-side of web projects
  • Desktop applications
  • Mobile applications
  • Serving applications that have a JavaScript API, such as Microsoft Excel
  • Applications for IoT devices.

According to many rated annual reports on GitHub and other resources dedicated to software and application development in 2017, 2018, 2019, JavaScript is one of 5 the most popular programming languages. At the end of 2018, JavaScript took the 1st place in terms of the popularity of its use in web application development. Thus, it is safe to say that JavaScript is one of the most popular web programming languages on the market. And JavaScript developers who own it are very popular programmers in the labor market.

Developing interactive Web pages and Web applications using JavaScript.

JavaScript is a programming language that makes it possible to implement complex web page behavior. Every time you see a web page, it not only displays static content but also does more – displays content updates on time, displays interactive maps, 2D / 3D animations, scrolls videos, etc. – it was not without the use of the JavaScript.

The standard HTML markup language allows you to quickly and easily create Web pages transmitted over the Internet. However, the pages loaded into the browser window are static. The user cannot change their content, cannot interact with them, except to read and view the images.

To make an HTML page dynamic, many technologies have been proposed and implemented to make HTML documents interactive and interacting with users. The Netscape has developed a special scripting language, JavaScript. Programs written in this language are embedded in an HTML document and interpreted by the browser used to view it. This technology relieves the load on the network, saving the user from unnecessary transfers of inaccurate information because now it is possible to write client-side code to validate the entered data.

The scripting language makes HTML pages interactive. The content of the page may depend on the user’s desire, however, to change it, it is still necessary to load a new page either in the frame of the displayed page or in a new browser window. Moreover, these changes are associated with the need to interact with controls: a button, an input field, a radio button, etc. All this is implemented using a dynamic page markup language (Dynamic HTML), which essentially consists of three components – a cascading style sheet ( CSS), JavaScript, and HTML connected by the Document Object Model (DOM).

These technologies are powerful tools for creating interactive Web pages, but they are limited by the capabilities of the corresponding scripting languages, which are directly related to the elements located on the page, specified by HTML tags.

The JavaScript as a modern web programming language and its frameworks

JavaScript frameworks exist to help us build powerful, powerful applications using a generic approach. JavaScript and other basic web technologies empower developers to do what they want without being constrained by the tools they use.

There are many frameworks written for JavaScript:

  • Frontend development – React, AngularJS or Vue
  • Backend development – Node.js, Express or Next.js
  • For working with databases – Redux
  • For mobile app development – React Native.

JavaScript as a Full Stack Development Language for Modern Applications.

Using only one JavaScript language with the necessary JS frameworks, you can conduct all FullStack development of most applications. And here Mean Stack is deservedly popular.

The Mean Stack is web development on a stack using tools like MongoDB, Express.js, Angular, and Node.js. Large technology companies, IT industry leaders, while developing their products and solutions in the JavaScript, actively use the Mean Stack.

The Angular.JS

The AngularJS is an open-source JavaScript framework. It is designed for developing single-page applications. Its goal is to extend MVC-based browser applications and make testing and development easier.

To describe the interface, declarative programming is used, and the business logic is separated from the interface code, which improves the testability and extensibility of applications.

Another distinctive feature of the AngularJS is two-way binding, which allows you to dynamically change data in one place in the interface while changing model data in another. This way the AngularJS keeps the model and view in sync.

Also, the AngularJS supports functionality such as Ajax, DOM manipulation, animation, templates, routing, and so on. The power of the framework, the availability of rich functionality has largely influenced the fact that it finds its application in an increasing number of web applications, being at the moment probably one of the most popular javascript frameworks.

What is a Node JS and what is the Node JS used for?

The Node.js platform made it possible to create both desktop and server applications using a single web programming language. But first of all, we are talking about the Node.js as a platform for building web applications.

Node JS Framework
Node JS Framework

The Node is a server-side JavaScript framework through the V8 engine. JavaScript does the action on the client-side and Node on the server. The Node.JS can work with external libraries, invoke commands from JavaScript code, and act as a web server.

The Node JS gives you the ability to run and execute JavaScript code without using a browser. This allowed JavaScript to move from a highly specialized, client-side, to a full-fledged web programming language.

The Node JS uses a modular system. That is, all built-in functionality is split into separate packages or modules. A module represents a block of code that can be reused in other modules. If necessary, we can connect the modules we need. What built-in modules are in node.js and what functionality they provide can be found in the documentation.

Scaling resources is easier with the Node. When thousands of users are simultaneously connected to the server, the Node works asynchronously, that is, it sets priorities and allocates resources more efficiently than Java. Java, for example, allocates a separate thread for each connection. The main goal of the Node.js is to build scalable network servers.

What can you create with Node.js?

With the Node.js, you can create a complete web application for the Internet, Linux, OS X, and Windows OS. The Node is handy for building APIs. You can write a cross-platform application in the Node.js. The Node is the foundation for the Internet of Things. Sensors, mobile devices, thermostats, switches, gadgets, etc. can all be enabled in the IoT through the use of the Node.js.

The MongoDB Database Management System

The MongoDB

MongoDB is the most popular database management system for the Node.js right now. To work with this platform, you first need to install the MongoDB server itself. In addition to the Mongo server itself, we need a driver to interact with the Node.js.

When connecting and interacting with a database in the MongoDB, the following stages can be distinguished:

  • Server connection
  • Getting a database object on the server
  • Getting a collection object in a database
  • Interacting with a collection (adding, deleting, getting, changing data).

What is TypeScript?

The TypeScript is a JavaScript-based programming language. But the TypeScript isn’t just a new JavaScript.

TypeScript is a strongly typed and compiled language, which is perhaps closer to the programmers of Java, C #, and other strongly typed languages. Strong typing reduces the potential for errors that could arise when developing in JavaScript.

The TypeScript implements many of the concepts that are inherent in object-oriented languages, such as inheritance, polymorphism, encapsulation and access modifiers, and so on.

The capabilities of the TypeScript make it faster and easier to create large, complex programs, and therefore easier to maintain, develop, scale, and test than in standard JavaScript.

The TypeScript develops as an open-source project and is cross-platform, so we can use both Windows and macOS or Linux for development.

TypeScript is a superset of JavaScript, which means that any JS program is a TypeScript program. In TS, you can use all those constructions that are used in JS – the same operators, conditional, looping constructs. Moreover, the TS code is compiled into javascript. TS is a modern tool that makes it easy to develop any applications for any purpose.

The React.js and Vue.js for user interface development

The React (React.js or ReactJS) is an open-source JavaScript library for developing user interfaces. The React.js is developed and maintained by Facebook, Instagram, and the community of individual developers and companies.

The ReactJS can be used to develop a single page and mobile apps. Its goal is to provide high speed, simplicity, and scalability. As a library for developing user interfaces, the React is often used with other libraries such as Redux.

The Vue.js is an open-source JavaScript framework for building user interfaces. Easily integrates into projects using other JavaScript libraries. The Vue.js can function as a web framework for developing reactive style single-page applications.

The Babylon JS and Three JS for 2D and 3D graphics

The Babylon.js is a simple cross-browser JavaScript framework that uses the WebGL API to display 2D and 3D graphics in the browser without using any third-party plugins or add-ons.

The Babylon.js uses the HTML5 Canvas element. The framework is distributed under the Apache 2 license.

The Three.js is a lightweight cross-browser JavaScript library used to create and display animated 3D computer graphics for web application development. The Three.js scripts can be used in conjunction with the HTML5, CANVAS, SVG, or WebGL element. The source code is located in the GitHub repository.
