We asked members of the JavaScript community to share their “pick of the year”

My 2025 Pick: Delba Oliveira

My pick of the year is Delba Oliveira from the Next.js team. Her work across the ecosystem is remarkable. She has a rare ability to make complex topics feel simple while consistently delivering deeply practical guidance for modern Next.js, React and JS.

New Proposals

While Temporal still tops the rankings, excitement is down from last year, which makes sense as it has begun its transition from theoretical proposal to actually being implemented in Firefox.

Missing Features

No change in ranking in the top 5, but it's notable to see that interest in Signals did drop slightly compared to last year.

Native Types

While 32% of respondents are hoping for in-browser runtime types support in JavaScript, if types are ever officially supported it seems much more likely to be through TypeScript-like type annotations, which came in at number one.
How would you like to see types implemented natively in JavaScript?

Pace of Change
✨

This question's aim was to get a rough idea of how well respondents are keeping up with new features, and it shows that most of us struggle to learn about–let alone try out–new language features Hopefully this is something these survey results can help with!

Reading List

The Reading List lets respondents learn more about specific items post-survey, and this year we tweaked it to support auto-adding items based on survey answers, in addition to letting respondents select items manually. This change led to a much more library-focused list, compared to previous years which included more features.
