测试工具随时间变化的比率

While Jest has long enjoyed a comfortable spot as the most-used testing tool, Vitest is climbing the ranks so fast that it wouldn't be surprising to see it overtake it in the upcoming year, especially with Jest's satisfaction ratio trending down.

Meanwhile, Storybook is an interesting case study in a project trying its best to address its users' frustrations. It's still showing a slight satisfaction loss compared to last year, but the rate of decline has slowed, and things might start looking up soon.

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

My 2025 Pick: SST

I didn't know about SST just a year ago, but I started using it for a new work project and it's been fanstastic! It really deserves more exposure.
