Also featured: a browser email verification API proposal, an article on building browser text editors, linter autofix pitfalls, and opinions on major version bumps being user-hostile. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Is Remix 3 still built on React? No, Remix 3 removes its React dependency and becomes an independent full-stack framework distributed as a single npm package. The release candidate represents the near-final version of this rewrite from its earlier identity as a React-based framework, with the final release targeted for October 2. _Track framework migrations like the Remix 3 rewrite as you plan your own stack on daily.dev._ ### How small can a working Minesweeper implementation in JavaScript be? A playable 8x8 Minesweeper game with flags and cascading blank cell reveals has been implemented in a single line of JavaScript totaling 247 bytes, which is 62% smaller than an earlier 658-byte version by the same author. The reduction relies on a series of code-golf tricks to compress the logic. _Developers exploring code-golf and minimal JavaScript techniques can find similar deep dives on daily.dev._ ### What problem can occur when a linter applies multiple autofixes at once? Applying several autofixes simultaneously can produce broken code that a sequential fix-then-reanalyze approach would avoid, because concurrent fixes may conflict with each other's assumptions about the code state. This highlights a tradeoff between speed and correctness in linter tooling design. _Anyone tuning linter workflows can keep up with tooling tradeoffs like this on daily.dev._ ## Community discussion Top comments from developers on daily.dev. **@pdfopsdev** · 0 upvotes > 247 bytes for a playable minesweeper is wild but the real lesson from code golf like this is what actually costs bytes, property names and control flow, not logic. same trick applies keeping a Workers script under the free-tier bundle cap, minifying identifiers buys you way more than you'd expect. ## Similar posts on daily.dev -
