Denys is a frontend developer & public speaker. Being 2-in-1: an art school graduate and an engineer, Denys is passionate about psychology, physics, history, drawing, literature. In his day-to-day job, he enjoys getting to the heart of the matter of things and processes.
Wading through the thicket of frontend technologies, during his career, Denys had a chance to work with design, to master the “CSS side” of the stack, and to enjoy architecting UX. However, for the last years, Denys has been building Javascript applications of different levels of complexity.
Denys Mishunov recently discussed what “Frankenstein Migration” is, compared it to conventional types of migrations, and mentioned two main building blocks: microservices and Web Components. He also showed you a theoretical basis of how this type of migration works. If you didn’t read or forgot that discussion, you might want to get back to Part 1 first because it helps to understand everything we’ll cover in this second part of the article.

What if you spend the unproportionate amount of time to support an outdated system?
The typical answer to such a problem is the migration of the application. However, all of the front-end frameworks are different. In this article, Denys Mishunov will show you “Frankenstein Migration” which is a new, framework-agnostic approach to the process of migration that allows using the same mechanism to migrate to pretty much any framework of your choice.

When Denys Mishunov was invited to speak at one of the best front-end conferences in Europe, he felt like he did not deserve to be at that conference. And he didn’t even know that those feelings of his had a name! This is called impostor syndrome and it is a real psychological issue, rooted deeply in many of us. If we do not pay attention to its symptoms, if we blindly follow its triggers, then we can get into real psychological trouble. The good news is that, even though there is no pill for it, we can change out attitude towards it. Simply acknowledging the feeling can help to neutralize its effect.

When we talk about the user’s perception of time, we mean psychological time, or brain time. This time is of interest to psychologists, neuroscientists and odd individuals like me. Objective time is dealt with by technical means, and those means have limits that become insurmountable at some point. As web developers, we should aim to deliver fast and reliable web services to make users feel comfortable. We can use technological means to control the objective performance of a website. However, technology and resources eventually hit a limit, at which point it becomes difficult to change objective performance. Then, we have to aim to exploit what psychology and neuroscience tell us.

In this article, Denys Mishunov aims to provide you with the reasons and theories for why things function in certain way. He will use examples that are observable in the offline world and, using principles of psychology, research and analysis in psychophysics and neuroscience, he will try to answer some “Why?” questions. Denys will also cover psychological aspects of some practical cases, like performance optimization of an existing project, how to deal with the better performance of a competitor’s website and how to make users barely notice any waiting for your services.
