> One of the advantages of this API is that you don't have to use a library for this kind of job anymore. The majority of browsers are providing a lot of support for some of the newest and awesome APIs, and this has been improving the experience for users in general, allowing developers to use some native browser APIs and reducing their final code bundle.

"Why Svelte is our choice for a large web project in 2020", Ryan Atkinson (@ryanatkn) #svelte #spa

Thu Mar 12 10:05:18 2020 - sharemarks svelte spa

> Svelte provides an enjoyable DX that doesn’t compromise on UX. I think it’ll soon become common knowledge among UI developers that compilers have an advantage over runtime-only frameworks for hitting this sweet spot.
> […]
> We’re happy to pay the costs of early adoption when a technology provides significant advantages, and that’s our bet for Svelte.

> I love improvements that just work without any effort required of website owners. […] The less friction we can add to introduce these improvements, the more likely they will be adopted, and there’s no better friction than none at all! Fixing the impact of layout shifts on users for responsive images seems to be one such improvement and the web is all the better for it.

"The performance benefits of Variable Fonts", Mandy Michael (@Mandy_Kerr)

Thu Mar 12 09:46:25 2020 - boostmarks fonts variable-fonts

> Variable fonts reduce the overall combined file size and automatically reduce the number of network requests by simply being a variable font.
> Even if you consider the slightly larger file sizes, when combined with improved font compression formats like WOFF2, font subsetting and font loading techniques like `font-display: swap;` we end up in a situation where we can still get smaller overall font file sizes as well as a significant increase in stylistic opportunity.

> Your language isn't broken, it's doing floating point math. Computers can only natively store integers, so they need some way of representing decimal numbers. This representation comes with some degree of inaccuracy. That's why, more often than not, .1 + .2 != .3.

> To make sure our apps are as reliable and accessible as possible, especially in an increasingly globalized marketplace, we need to support constrained devices—they're how most users are accessing the web globally. OMT offers a promising way to increase performance on such devices without adversely affecting users of high-end devices.

> Sans accessibilité réelle, ces outils ne fonctionnent pas bien. Sans accessibilité réelle, les personnes handicapées seront toujours handicapées par l’inaccessibilité des sites web. C’est une aberration de vendre ces outils en les opposants à la mise en accessibilité d’un site web. Oui, c’est moins cher mais c’est parce que ce n’est pas du tout la même chose.

> A lot of performance issues stem from them simply not being very noticeable to those of us doing the building. Changing that wherever we can is one of the best ways to make sure that all that low-hanging fruit doesn’t go overlooked.
