The Web Almanac 2022's Take on the State of JavaScript (As It Is Used)— What’s better: a survey, or real world usage data from 8 million Web sites? If you prefer the latter, this is for you. The Web Almanac is an annual ‘state of the web’ report into what technologies are being used online and amongst the over 20 chapters of insights is a JavaScript-specific chapter. Some highlights:
- More JavaScript is going over the wire than ever before. 1.3MB for a page only puts you at the 90th percentile(!) About half of it goes unused too..
- 77% of mobile pages have render-blocking scripts in
<head> - Dynamic import is barely used – about 0.3-0.4% of pages.
- Web workers are used on 12% of pages.
- Of the 1,000 most popular sites, 17% use webpack, about 1.5% for Parcel.
- Psst.. jQuery is still used all over the place..
