We're starting 2021 strong with a new edition of the Front End Performance Checklist. Next, come the results for the State of JS survey, an extra trend report for State of CSS. And we have multiple updates from Node, Gatsby, Jeckyl, and the new Typescript 4.2 Beta.

Smashing Magazine's Front End Performance Checklist for 2021

The New Year Front End Performance Checklist is already an established tradition. And this year's entry is gigantic. Bookmark it, download it, and start applying the advice to make your web pages and apps faster and leaner.

The State of JS 2020 results

We got the results of this survey, and the results came from over 23,000 replies. There is a lot of useful and interesting information packed here, but I'm going to give you a teaser. To no surprise, React, Vue, Angular, and Svelte lead the pack in terms of satisfaction, interest, usage, and awareness. For more, be sure to check the full report.

The results for The State of CSS 2020 came out last year, and I did cover them at that time. This is a report that compiles all the data in a very nice presentation worthy of any conference.

Browser news


The WebKit team released the 118th iteration of the Technology Preview. The thing that I'm most excited about is the support for the aspect-ratio feature. Of course, there's a lot more than that, but you'll have to check the release notes to find out.
