Web programming

Nowadays, web programming is one of the most promising fields of activity. In today’s world, if any business does not have its own website, it is far behind its competitors.

To create interactive and compact web applications, it is necessary to know a lot of modern web standards. We do not pretend to be a comprehensive description of these standards, however, we have tried to collect a lot of interesting material that will serve as a good impetus for beginning web programmers.

Why Web Programming?

The rapid development of the Internet over the past couple of years has led to an increase in the number of new online services. Starting from the initial characteristics and basic services available to users (e-mail and the web), the Internet has developed into a large worldwide web with a large number of different services, technological solutions and has become the place where business organizations from all over the world meet.
There is an increase in the number of companies switching to electronic business. They open their corporate domains, create their websites, advertise their goods and services on the Internet, launch online sales.

The main role in the technical part of this work will belong to web programmers and developers. Their tasks:

  • create websites
  • html layout
  • connect them to the corresponding database
  • write web servlets
  • create web services
  • connect to the Internet
  • create web applications for various purposes
  • create technical prerequisites for online sales and promotion of goods and services
  • take care of the security of websites and web servers
  • optimize customers’ existing web applications
  • make it possible to automate the publication of content

Basic concepts

Web programming is the creation of sites and applications that run on the web. Special computer programs are created – scripts, which are divided into two types: server and client. The server is a computer on which site files are located. The client is the user himself, or to be more precise, the browser installed on the PC. When submitting a request to the server, it acts as a client.
The link between the web developer and the sites is the web programming language. There are many languages ​​in which both server and client scripts are written. But some languages, on the contrary, are used exclusively for server or client scripts.

Web programming technologies

Web design

  • The HTML markup language is the code used to structure and display a web page and its content
  • CSS is actually a stylesheet language that is responsible for displaying HTML documents. CSS works with fonts, with character and background colors, with margins, with lines, with the height and with the width of display elements, with background images, with the positioning of elements and much more
  • SASS is a CSS preprocessor that can reduce the amount of repetitive CSS code and save time. This is a more stable CSS extension that clearly and structurally describes document styles.
  • LESS is an extension to CSS. It has all the basic capabilities of preprocessors and even more, but does not have conditional structures and loops in the usual sense. Its main advantage is its simplicity, practically standard syntax for CSS and the possibility of expanding the functionality due to the system of plugins

Client-side programming

  • The JavaScript programming language is the most popular and supported by all modern Internet browsers. It is designed to make web pages come alive. Scripts in the browser connect directly to HTML and are executed as soon as the page is loaded
  • React is a JavaScript library used to create user interfaces
    VueJS is a JavaScript library for creating web interfaces using the Model-View-ViewModel (MVVM) architecture pattern.
    AngularJS is a JavaScript framework designed for creating single-page web applications
  • jQuery is a JavaScript library designed to simplify scripting when working with HTML element nodes in a browser or for working in a browser without a GUI
  • AJAX is a library that greatly simplifies and speeds up the writing of JavaScript code, and also allows you to work with all browsers

Server-side programming

  • The PHP programming language is the most popular server-side web programming language. PHP is supported by most hosting providers
  • Node.js is an environment for running your JavaScript code, it’s just another way to run code on your computer
  • ASP.NET. — a low-code web application development model that includes the services needed to build enterprise web applications
    Python is a general-purpose programming language aimed primarily at increasing the productivity of the programmer himself
  • Ruby on Rails is an open source, web-oriented development environment optimized for ease of programming and robust performance
  • Thus, by combining different technologies, whether they are client or server, the developer can get a large number of different interactive possibilities.

Web programming at KPI

Summing up, I would like to note that web developers are the same as programmers, because both positions have similar requirements for skills and abilities. Web developers use skills and tools that programmers will never use, such as various graphic design and video editing tools. In addition, web developers usually contact their customers more often than programmers.

If you don’t know where to start studying programming, you want to study the basics of web programming and information technologies in detail – we invite you to study at our Kyiv Polytechnic University named after Igor Sikorsky at the APEPS department, and we guarantee that upon graduation, you will really be a professional web- developer!
