This year marks the 10th anniversary of the Fronteers conference , held at Pathé Tuschinski in Amsterdam. A single track conference covering various topics of frontend development. The JDriven delegation this year consists of Patrick Ooteman, Auke Speksnijder and Martijn van der Wijst. Topics are: VR, Animations, Developer tools, Caching, a11y, and WebAssembly.
We need browser wars
To start off, Niels Leenheer gives a talk about the importance of when to use and also when not to use progressive enhancement. You can imagine that a video tag can be replaced by an image for devices that don’t support the native video tag. But Youtube without videos, yeah, that won’t work at all. After the audience loudly applaudes to an image of ‘goodbye Internet Explorer’, he emphasises that browser wars are a good thing. When every browser would run on Webkit (or nowadays even Chromium), the need to make browsers better would decrease. Also he said:
IE6 was a good browser
Daring statement! But then when you think about it, at the time it could do awesome things. IE6 became a pain in the ass for developers only later, when modern browsers came around and people were still using IE6. Key takeaway of the talk: think about users, not about browsers.
Jessica Rose was next to talk about Imposter Syndrome . A lot of people suffer from it. Amongst us 3, we all - to some or more extend - experienced moments of feeling inadequate at the jobs we have been doing. To deal better with the feeling of knowing nothing, Jessica explains that you could either be more friendly, work harder or find your sweet spot for learning to become better. The learning goal at hand should not be too easy and not be too hard, so progress can, and actually will be made.
Cool debugging features
Next up is Umar Hansa . He talks about new features of the Chrome (canary) devTools. We all find this the most interesting talk of the day. We can write a whole blog post about all the features covered! Though let’s list some cool features already:
Open a run command box (like in VSCode) with CMD + SHIFT + P
Take a screenshot of a whole page or single elements
Saving of code snippets for use over multiple web sites
Real-time code coverage panel that shows which parts of the code and CSS are (not) being used.
There’s a terminal in devTools!Umar Hansa showing terminal in the chrome canary dev tools at Fronteers conference
You can import src files and save them while debugging and making changes. You can even do some sort of Git diff.

Yoav Weiss gave a very in-depth talk about caching. According to him the two hardest things for a developer are:
Naming things, and
But caching is important. Only there are so many options!
You can read most of what he talked about in Yoav’s own blogpost .
Internet for everyone
Accessibility (a11y) is a returning hot topic at Fronteers. Multiple talks spend some time about it. Alice Boxhall gives some nice insights in how to apply accessibility in your daily development work. E.g. you can use the devTools to inspect the accessibility tree (OAM) which is being used by screen readers by using an accessibility API . This way you can debug the robustness of your application. 'Robustness' being one of the four keys of accessibility guidelines set up by the The Web Content Accessibility Guidelines (WCAG :
Web content should be perceivable, operable, understandable and robust
User interactions require ability. The less an interface requires of its users, the more accessible it is. To have a very bad accessibility experience, visit: [dontclick.it](http://dontclick.it)
Accessibility has 6 syllables
Ashley Bischoff is very elaborate on how language should be optimised for every reader of your text. This talk felt a bit like being back in college. But we all write documentation, content or presentations. So knowing some easy steps to improve on them is very welcome. Some pointers:
Use Maximum of 20 - 25 words per sentence
Use variety of word lengths, but as short as possible.
[bit.ly/plainwords](http://bit.ly/plainwords) is a tool that gives you shorter synonyms for words.
[bit.ly/readinganalyzer](http://bit.ly/readinganalyzer) is a tool that analyses the difficulty of your text.
Fronteers Jam Sessions
If you ever visit fronteers, be sure not to miss the jam sessions, because those are very fun. There were talks of about 8 minutes each, each covering a subject either in more depth or with a lot more humor. Highlight of the Jam Sessions was the talk of [@stommepoes](https://twitter.com/stommepoes) about the evolution of icons and how to better apply them to our interfaces. Also we learned that Jake Archibald should always be mentioned. He made a nice interactive quiz, touching subjects around the quirks of frontend development.
Day 2 (by Auke)
On Friday there were also lots of interesting talks. We are not going to summarize them all, but here are some that we found interesting.
In the morning there was a good talk about testing. Alicia Sedlock touched on different kind of testing levels and which tools you could use to do that with. A funny example is the gremlins.js monkey/chaos testing library which can be used to test the robustness of your web application. Key takeaway for us is: test components instead of whole pages to prevent false positives in your test results.
Ash Kyd talked about Web Assembly or wasm and its benefits. Wasm is:
Not a language
You can write your code in C/C++/Rust, compile it to wasm and run it in the browser. There is a nice demo on the website of WebAssembly.org which shows a ported version of the game Tanks . Web Assembly is still under construction. It is currently being designed as an open standard by a W3C Community Group that includes representatives from all major browsers.
The nice thing about Fronteers is the talks cover a broad range of subjects. It once again becomes clear how diverse the field of frontend development is. On certain fields you’re much more experienced than others. Which is fine. We don’t need to be experts in all fields, but we can choose a speciality. We should always think about the user and the interaction possibilities of our products. It’s getting easier to include accessibility improvements into our development workflow. So let’s make the web easier for everyone.
