ES6 const is not constant or immutable

I gave a quick talk on JS a while ago on hoisting in JS and while discussing on how hoisting apply to variable declarations, we imminently reached to ES6’s let and const. So we began talking about the difference between var, let and const and how const is not really a constant or immutable.

Use a given version of Node.js on a Jenkins project

Like many others, we’re using Jenkins at Caphyon for tasks like testing or deploying some of our projects. These days I had to figure out a way to have a different Node.js version on a Jenkins project bound to a branch I was working on.


Hoisting in JavaScript

Two weeks ago I gave a lightning talk at Caphyon on hoisting in JavaScript. Putting aside all the common jokes about the JS language, people really seemed to like it. It was kind of a challenge to talk about JS while having an audience of C++ and Java colleagues.

Now getting back to the talk, that was lightning ⚡️ fast and it didn’t covered that much as I would’ve liked to. So I’ll try to write a bit more on JavaScript scoping and hoisting bellow.

Sticky table th's with position:sticky

Remember the last web app you’re working on it that had a large table with lots of data rows? Feels like yesterday, no? Well, having this scenario, in terms of UX, it’s almost mandatory to have thead’s or tr’s stuck while browsing the tabular data.

Thoughts on accessibility

As a person who mainly works on small teams, I always felt guilty of making accessibility a lower priority. The reasons were multiple and it’s hard to blame someone else other than me.

Over time, I read lots of good articles on accessibility but couple of months ago, I stumbled upon this incredible article by Tuukka Ojala. Both incredible and inspiring, that article remained stuck in my head and hopefully will change the way I write HTML and not only.


I made the switch to catalin.red

I’ve never been a big fan of my very own domain name. Besides the fact that it was quite long, I really hated the hyphens for red-team-design.com.

Two hyphens, the mistakes of my youth.

Visually validate an input field using CSS

While working on this site, I tried to improve my email subscription box a little bit. The idea was to enable the action button only when the user types something in the email input. So I found a way to use :placeholder-shown CSS pseudo-class in an attempt to visually validate an input before form submission.
