Boost your front-end skills

iframe, or not, that is the question

posted in JavaScript on 2016-04-09

One of the things that I really like at work is the fact that we spend time in research tickets. We have unknowns and we make a research to find out more information on particular topic. We then base our decisions on the results. Recently we had to decide whether to use an <iframe> for a third party widget development. I feel that the collected information may be handy to someone else so I decided to write it down here.

The earthquake in the JavaScript community

posted in JavaScript on 2016-03-25

You probably heard about Kik, NPM and left-pad saga this week. Shortly, a company Kik asked a developer Azer Koçulu to give the ownership on a NPM module. The module name matches the name of the company. The developer refuses and the company reaches the registry (NPM). The module was transfered to the company based on a NPM policy. The developer then decided to remove all his modules from the registry. The bad thing is that one of these modules left-pad is a dependency of many other modules. As a result of the un-publishing all the packages that depend on left-pad can not be built. Some really popular tools like Babel and React started getting broken builds.

The last job on Earth

posted in Inspiration on 2016-02-18

Did you know that in the next 30 years 50% of the jobs will go away because we'll get machines doing them. I have the good feeling that my job (programming) is not in those 50%. Or maybe it is :)

Meet sequence expression

posted in JavaScript on 2016-02-02

You have no idea how fun is to transpiler JavaScript. I’m digging into that last few weeks and there is a step where I have to transform an AST into valid code. There is one tree node which I really like - sequence expression.

Unexpected usage of Array.length

posted in JavaScript on 2016-01-14

I like reading code of other developers. It’s a nice way to learn patterns, techniques and small tricks. Recently I found something about Array.prototype.length which caught my attention.

The return statement is not the end (but it should be)

posted in JavaScript on 2016-01-05

Well, I kind of lied in the title of this article. Of course that it is the end of the function. Once we call return everything else after that is simply not executed. Ops … I did it again, I kind of lied again.
