What is the difference between Shadow DOM and Virtual DOM?

Mon, 16 Sep 2019 06:30:35 +0000

DOM (Document Object Model) is a fundamental concept in front-end, and for sure, everyone who tried to learn programming has heard about it more than once. For beginners, it’s not so easy to understand what it exactly is and how to manipulate it. DOM manipulation isn’t so easy and comfortable, and the most important, it brings a lot of issues with performance. Nowadays, there are two essential concepts of DOM came with progressive web frameworks like Angular, React.js or Vue.js, Shadow DOM and Virtual DOM. In this article, I want to explain:what is the Document Object Model (DOM),

Why you should learn Python?

Thu, 12 Sep 2019 06:28:23 +0000

Python is one of the most popular and widely used programming languages of today. It’s applied by beginners and professionals, startups and large companies, academia and commercial entities. As a general-purpose and multi-platform programming language, it has a variety of applications. Python and most of the stuff in its ecosystem are free and open-source. There is a large, dedicated, and friendly community of developers and educators who support the development of Python and the related libraries and help people learn and master Python.

How to Start with Machine Learning?

Thu, 22 Aug 2019 06:08:36 +0000

Machine learning is about using sample data to build mathematical models that enable computer systems to perform tasks without obtaining explicit instructions. Image recognition, self-driving vehicles, Internet search engines, computer vision, spam email filtering, and many other systems use machine learning. It’s also applied in financial forecasts, medical diagnostics, fraud detection, and so on.

Machine learning is a vast and promising area. It offers exciting solutions to real-world problems as well as a variety of well-paid jobs.

What’s new in ECMAScript 2019 (ES2019)?

Mon, 19 Aug 2019 06:42:24 +0000

Every year since 2015, new ECMAScript features are released. Creating a new ECMAScript standard has four stages, from stage 0 to stage 3 it is mostly planning, and drafts and stage 4 is final. It’s possible to use the newest features in Google Chrome version 72. Let’s take a look at what exactly ES2019 brings us:

Object.fromEntries(),
trimStart() and trimEnd(),
flat(),
flatMap(),
Symbol object description property,
catch optional binging,
well formatted JSON.stringify,

Let’s go one by one and check how we can use this brilliant new features.

Object-oriented programming in Python

Thu, 15 Aug 2019 07:11:48 +0000

Python allows writing programs following several programming paradigms (like procedural programming, functional programming, object-oriented programming) and to combine them.

Object-oriented programming is one of the most widely used paradigms today. It is based on the use of objects, entities that contain data members called attributes and bounded functions (routines, procedures) called methods.

Objects are instances of classes. In other words, classes mostly define the structure of objects and serve as templates for creating them. Classes have methods definitions but can also contain data common for all their instances.

5 reasons why you should learn Javascript

Mon, 12 Aug 2019 06:39:12 +0000

Javascript is one of the most popular programming languages in previous years, but lots of people still ask the question, why it’s worth to learn JS. Since a few years, Javascript spread so much that it’s visible almost everywhere, front-end, back-end and even mobile development and the popularity of this programming language is not getting smaller. There are tones of different frameworks which grown on Javascript basics and are used almost in every project which needs any user interface. Taking into consideration this information, I’ll try to describe to you a few reasons why it’s still a great idea to learn Javascript in this article.

Loops in Python – comparison and performance

Thu, 08 Aug 2019 06:48:04 +0000

Python is one of the most popular programming languages today. It’s an interpreted and high-level language with elegant and readable syntax. However, Python is generally significantly slower than Java, C#, and especially C, C++, or Fortran. Sometimes performance issues and bottlenecks might seriously affect the usability of applications.

Fortunately, in most cases, there are solutions to improve the performance of Python programs. There are choices developers can take to improve the speed of their code. For example, the general advice is to use optimized Python built-in or third-party routines, usually written in C or Cython. Besides, it’s faster to work with local variables than with globals, so it’s a good practice to copy a global variable to a local before the loop. And so on.

Let’s get started.

For loop, while loop, do…while loop and other JavaScript loops – comparison and performance

Mon, 29 Jul 2019 07:18:15 +0000

Loops play an essential role in software development, and they are used to iterate through the arrays or other elements that are iterable. In Javascript, we have a few different types of loops. It sometimes can be confusing which loop we should use in a particular case and which one will be the best in case of our performance. In this article, I’m going to compare the loops in Javascript, describe their pros and cons, test the speed of each of them.

Differences between Artificial Intelligence and Machine Learning and why it’s important for us

Fri, 03 May 2019 15:36:35 +0000

Artificial intelligence (AI) is everywhere around us: image recognition and contacts suggestions on Facebook or Twitter, self-driving cars, software that beats champions in chess and go, books recommendations on Amazon, Google search, Apple Siri and Microsoft Cortana, and so on. It became a very important aspect of our lives. Its importance raises, and we rely on AI more and more every day hoping that it’s going to improve our well-being.

What is functional programming and it’s most important aspects?

Fri, 12 Apr 2019 09:42:04 +0000

Intro to what is functional programming

Functional programming is an interesting programming concept which gains a lot of attention lately. This article presents some of the most important aspects of functional programming in general and provides several examples in Python.

Functional programming is a kind of the declarative programming paradigm where functions represent relations among objects, like in mathematics. Thus, functions are much more than ordinary routines.

This programming paradigm can be implemented in a variety of languages. There are several functional programming languages such as Closure, Erlang or Haskel. Many languages support functional programming in addition to other paradigms: C++, C#, F#, Java, Python, JavaScript and others.
