The Web Weekly newsletter keeps you up to date, teaches you web development tricks and covers all things working in tech.

Moin moin, friends. πŸ‘‹

And a big hello to all the new subscribers! Almost 300 people subscribed to this newsletter in the last three days. 😲 I'm super excited to have you around!

But let me ask you, how did you find out about this newsletter? I couldn't figure it out yet; hit reply and let me know.

Before we jump into things from last week, let's google "text adventure" and open the JavaScript console. I love a good easter egg! πŸ₯š

Would you like to play a game? (yes/no)

This week's Web Weekly includes:

  • Accessible tables and crossed-out content
  • The web on iOS
  • Rendering of React components

... and, as always, GitHub repositories, a new Tiny Helper and some music.

Ready? Steady. Go!

A denial-of-service (DoS) attack against Unix-based systems

WARNING! These examples may crash your computer if executed.

Can you imagine what this snippet does :(){ :|:& };:?

This shell function (yes, it's a function!) is called a "Fork bomb", and it can make your machine unusable. Vivek Gite explains how it works and how you can prevent weird character combinations from taking over your computer.

Skills you must develop to become an executive

As you grow as a leader, your scope increases, the problems are increasingly ambiguous, and the solutions are unclear. Though you might have the knowledge to tackle these challenges, you might not be prepared for the emotional ups and downs.

Do you want to be a CEO or CTO one day? If so, I enjoyed this post from Nikhyl Singhal. Nikhyl describes the skills you need as an executive and how to develop them.

Accessible strikethrough content

The s element – Use the s element to highlight contents that are no longer accurate or no longer relevant. A typical example is the old and the new price for a product.

I learned about the s and del HTML elements this week. Check out Manuel Matuzovic's post about strikethrough content such as old prices.

The web that falls behind on iOS

So it’s not just one browser that falls behind. It’s all browsers on iOS. The whole web on iOS falls behind. And iOS has become so important that the entire web platform is being held back as a result.

Niels Lehnheer published an excellent article covering that every browser on iOS is forced to use Webkit. Is the web falling behind on one of the major mobile operating systems? It seems so.

All you have to know about JavaScript events

JavaScript Eventing Deep Dive – preventDefault and stopPropagation: when to use which and what exactly each method does.

I still remember how confused I was when I discovered JavaScript event capturing and bubbling. Thomas Steiner and Stephen Stchur explain everything you need to know about JavaScript events (and I finally understood when to use stopImmediatePropagation).

Code runs on people

We get it, you're clever. But the business doesn't need clever. It needs code that is only as complicated as absolutely necessary to get the job done. Anything else is just wasted effort.

The post "Code runs on people" on the blog (so worth subscribing to!) is a valuable reminder of why code should be as boring as possible.

A visual guide to React rendering

React components that show when they rerender

When does React re-render components? Alex Sidorenko works on a detailed series including many visual examples covering useMemo, props handling and many more cases.

Understand React rendering

Accessible tables

Resources for building accessible tables

Here's one for your accessibility bookmarks: Raghavendra Satish Peri collected resources that help you make your tables accessible. πŸ”–

(Pssst! 🀫 I'm collecting accessibility resources, too)

TIL recap: form validation with requestSubmit

DevSheet showing that calling `requestSubmit` triggers a form validation

To keep the articles on the blog up-to-date, I decided to reread and include older today I learned posts in this newsletter. πŸ˜‰

Did you already run into the problem that calling submit on a form element doesn't trigger the included form validation? If so, have a look at requestSubmit. It's a method that makes form handling in JavaScript way easier!

Start using requestSubmit

A quote to think about

This week's quote comes from the book that I'm reading, "On Writing Well". It teaches how to improve your writing style, use good language and engage the reader. I still enjoy reading it a lot!

Clear thinking becomes clear writing; one can't exist without the other.

This week's track is an absolute house classic. KΓΆlsch's "Cassiopeia" is a nicely rolling house track from 2014.
