Testing Tools Ratios Over Time

Vitest displays the classic signs of a technology at the start of its lifespan: high retention and interest, but low adoption in large companies – for now.

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

My 2024 Pick: Shruti Kapoor

My Pick of the Year is my friend Shruti Kapoor. Shruti has a way of explaining even the trickiest technical JS concepts in very easy-to-understand way. In her fun and engaging YouTube videos and conference talks, she teaches her audience the most critical parts of JavaScript development without a lot of fluff.
