Grid system in Bootstrap 4

unevenCols smallBootstrap 4 is not released officially yet, but at the time of writing this post there is 4.0.0-alpha.6 available. I have had a chance to play with a grid system in both: version 3 and 4 so I am here to show you how it works in real life scenarios. They do not differ much but if you have not had worked with Bootstrap's solution to responsive design, you should like it.

Adding rows to HTML table with jQuery When you have to dynamically add content to an HTML table in JavaScript, jQuery comes in handy. Although, it is not as simple as it could be expected. If you think there is a function like addRow(rowId, dataArray), I have to dispel the doubts, there is not. Nevertheless, a table can be updated in a few lines of code.

Two equality operands (== and ===) in JavaScript Do you use == or === in JavaScript? Or does it depend? Do you know what is the difference between them? I decided to write something about it because I think it is important to know those things when you create JavaScript code. Once I heard == and === in JavaScript are like == and equal in Java. This is far from the truth. Or actually it could be said that using == in JavaScript and == for comparing Strings in Java is WRONG.

Full reinstall of Node.js >Node.js reinstallation is an often solution to problems with frontend packages. I described one of them a few weeks ago - npm ERR! peerinvalid. What is funny, recently I have got a few different NPM errors on different computers. A solution was one - Node.js reinstallation. Although it seems straight forward, sometimes it is not. In one of my cases Node.js was so old that the new installation package could not find it and delete it properly so I had to do it manually. This post describes the steps of removing Node.js completely from a computer to make place for a new installation.

How it feels to learn JavaScript in 2016 This time I would like to share an article not written by myself, but one that I read and I liked. It is a subjective view on the JavaScript world with all those SomethingJS libraries. The author noticed the clearly visible problem of constantly changing trends and described it in an interesting way.
