My point being that it’s hard to write valid markup

JavaScript performance is bananas, a thread.

Let's write a function to sum the values from a the 'val' property of each element in an array:

function sum(arr) {
let acc = 0;
for (let i = 0; i < arr.length; i++) {
acc += arr[i].val;
}
return acc;
}

WCAG 3 will use a new color contrast method called APCA (Advanced Perceptual Contrast Algorithm).

It's a big improvement over the current system but there are a lot of changes to get your head around.

Serious question...

The last version of Express was published over 3 years ago! So why are we still using it today?

[Eric Bidelman @ebidel]

Amaze! Being able to test diff screenreaders has never been easy. Most devs don't have the test machines or working knowledge of AT across platforms. Add Talkback for mobile testing -> take my 💰

🦮 OMG, there is a BrowserStack for assistive technology! Using https://t.co/fzP0lfUMHc you can test in many ATs without installing them or changing your OS settings.

[Dominic Nguyen @domyen]

📐Storybook Measure is coming to 6.3!

It shows you margin, padding, and dimensions of DOM elements when you hover on them.

That means you can spot check UI spacing in @storybookjs without loading devtools (heavy!).

👏 Big up to @winkerVSbecks
