I tried React Compiler today, and guess what… 😉 – by Nadia Makarevich
In this interesting article, the author explores the new React Compiler that aims to automatically memoize components, props, and hooks’ dependencies to prevent unnecessary re-renders. She tests the Compiler on simple examples and real-world applications, finding that while it performs well on simple cases, it struggles with more complex scenarios. The author identifies manual memoization techniques that can improve the Compiler’s performance and concludes that while the Compiler is a useful tool, developers still need to understand and use memo, useMemo, and useCallback to optimize React components effectively.
Elixir: validate map and structs keys for merging at compile time! – by Jakub Lambrych
This article showcases the importance of validating map and struct keys in Elixir at compile time. It explains that while Elixir and Ecto have built-in functions for runtime validation, it is more efficient to catch key conformity errors during compilation. The article introduces the KeyValidator macro, which allows for compile-time checks of map and struct keys.
Meta Open-Sources MEGALODON LLM for Efficient Long Sequence Modeling – by Anthony Alford
Researchers from Meta, the University of Southern California, Carnegie Mellon University, and the University of California San Diego have open-sourced MEGALODON, a large language model (LLM) with unlimited context length. MEGALODON outperforms a similarly-sized Llama 2 model on various benchmarks. MEGALODON achieves impressive improvements in training perplexity and downstream benchmarks, demonstrating its ability to model sequences of unlimited length. The code for MEGALODON is available on GitHub.
Slack Combines ASTs with Large Language Models to Automatically Convert 80% of 15,000 Unit Tests – by Eran Stiller
Slack used a combination of Abstract Syntax Trees (AST) and large language models (LLM) to automatically convert 80% of 15,000 unit tests from Enzyme to React Testing Library. The transition was prompted by Enzyme’s lack of support for React 18, leading to the need for compatibility with the latest React version. By observing how human developers approached the conversion, the team adopted a hybrid approach combining AST transformations with LLM capabilities, resulting in an 80% conversion success rate.

lol Apple Intelligence is dumb… – by Jeff Delaney
After the very expansive device, Apple Vision Pro, Apple announced the new "Apple Intelligence" feature that makes iPhones do "amazing" things with more intelligence like analyzing users’ photos and emails using AI. And our friend Jeff Delaney, from the Fireship channel, voices their doubts about this feature. He believes this feature is merely a marketing strategy by Apple to keep up with competitors and create FOMO (fear of missing out) among consumers.
Persist your React State in the Browser – by Ajey N
This great article talks about the problem of persisting React state in the browser and introduces the solution of using IndexedDB, which allows for storing large amounts of complex data and querying it efficiently. The use-db-state library is introduced as a custom React hook that simplifies working with IndexedDB, providing a familiar interface similar to useState. Various use cases for use-db-state are mentioned, such as persisting form data, user preferences, shopping carts, and more. Check it out!
