I'm working on a small library that has a logger. I'm bundling the app to a single file and I want to disable the logger for the production version. In this blog post we will see how I removed the logger.log calls from my bundle using AST (abstract syntax tree).

Sometimes when you learn something new you get really excited. Excited to that level so you want to teach it to someone. That is the case with the concept which I found a couple of months ago. It is an implementation of the command pattern using generators. Or the well known saga used in the redux-saga library. In this article we will see how the idea makes our asynchronous code simpler and easy to read. We will also implement it ourself using generators.

You probably know the famous quote that the code should be written for humans to understand and accidentally for computers to execute. Writing code that compiles is easy. Writing readable code is completely different thing. Working in a team is like sharing the kitchen with your roommates. You all should care for the dishes and keep clean. And it is not only because of the others but because of you. You don’t want your dinner in a mixed place and dirty dishes right.

The this keyword is always important in JavaScript. I'll admit that it took me some time to actually understand how it works. You know, sometimes JavaScript is all about the scope. Where you are and what you have an access to. This article is about the bind function. Something which I use very often.

This blog post is part of series about AbsurdJS. I'll continue filling the library with small and self organized black boxes. In the last article we talked about creating a JavaScript router. This time we will go through the process of making Ajax requests.

I was surprised by the good feedback for JavaScript template engine in just 20 lines and decided to blog for another small utility function which I'm using often. While we are talking about JavaScript in the browser, most of the operations are asynchronous. We are dealing with callbacks all the time and sometimes we end up with awesome callback hell.

I'll be honest and I'll say that I'm a bit lazy sometimes. I'm one of those developers which don't like to repeat same actions again and again. There are dozen of things which I have to do while working on a project. Very often I'm covering the development of several applications and have to switch between them. It's really annoying process. I hate to have many opened tabs in my browser, many consoles or several code editors. I always try to improve my productivity by automating tasks. I think that even switching between opened applications takes too much time.

I just noticed that the most popular repository in my GitHub account is EventBus. There is already an article about it, but it's a little bit outdated. I needed to clarify few things, so here is a new one.

While I'm working on Auxilio I end up in a sitatuation where I have to call few javascript functions in a sequence. It's an interesting how this could be solved and I'll be happy if you share your opinion for such problem.

Douglas Crockford’s Function Challenges. Test your knowledge of function scope and and learn to compose functions that can be called multiple times through function returns.

That's a great article by Robert C. Martin. It's one of those articles that really may change something in your programming. The principle is called Open-Closed and it says:_SOFTWARE ENTITIES (CLASSES, MODULES, FUNCTIONS, ETC.) SHOULD BE OPEN FOR EXTENSION, BUT CLOSED FOR MODIFICATION._More about that here.

A couple of days ago, I found very useful page about JavaScript called "JavaScript Garden". Check out here.JavaScript Garden is a growing collection of documentation about the most quirky parts of the JavaScript programming language. It gives advice to avoid common mistakes, subtle bugs, as well as performance issues and bad practices that non-expert JavaScript programmers may encounter on their endeavours into the depths of the language.

Finally I finished some bugs of my own project management system and I think it's ready for use. SVET is one of my biggest projects and it's a web based project management system, that helps you to organize your work. Basically it's an online notebook which you can use to store the information for your projects. It enables you to track your working time and communicate with your team and clients. You can also make detailed reports of what you've done for a specific period of time. Please check out here.
