You can get access to both through a lifetime deal in the FounderStack bundle*. On a less positive note, the subscriber count of this newsletter has been stagnating lately, which is a bit frustrating. If you enjoy it, I'd really appreciate it if you could share it with your friends or co-workers — it would mean a lot! Enjoy this issue and have a lovely week ☀️ Vue 📕 Vue's Magical Reactivity Has Some Quirks* 👉🏻 Why does Vue's reactivity sometimes behave unexpectedly? 👉🏻 Explore ref unwrapping edge cases and cloning complications with clear examples and fixes. 📕 Announcing Vitest 4.0 👉🏻 Browser Mode being marked stable. 👉🏻 Visual Regression testing support. 📹 Blazing Fast Vue.js with Vapor Mode 👉🏻 Vapor Mode is a new rendering strategy for Vue.js that skips the Virtual DOM, uses less memory, and produces tiny app bundles, similar to the strategies used by Solid.js and Svelte.
