posted in JavaScript on 2018-02-14   shell evala socket terminal app open browser term data web chrome

On my machine I have four applications always open - VSCode, Chrome, iTerm and Slack. I spend most of my time in Chrome and VSCode. My editor is full with awesome extensions and I feel pretty good there. What I am doing for the browser is making sure that I have fewer tabs open and install only extensions that I really use.

Dependency injection in JavaScript

posted in JavaScript on 2014-01-06   function var dependencies router service scope arguments deps dosomething

I like the quote that the programming is all about managing complexity. Maybe you've heard that the computer world is a giant construction of abstractions.

The languages which you use have build-in functionalities and they are probably abstracted functions of other low level operations. It's the same with JavaScript.
