The State of JS 2022 — The State of JS is one of the JavaScript ecosystem’s most popular surveys and this time 39,471 folks took part giving us a snapshot of the tools, technologies, and language features people are using (or not using!) There’s a lot to go through, but here are some key points:

• top-level await is the most newly adopted feature recently.
• The JavaScript / TypeScript balance shows a majority of developers using TypeScript over JS.
• Express remains by far the most popular backend framework with Nest, Fastify, Strapi, and Koa following somewhat behind.
• Other interesting results can be found in JS pain points, what is currently missing from JS, and the 'Awards' for stand out items (complete with snazzy visual effects).
