This is the third in my annual series reviewing everything that happened in the LLM space over the past 12 months. For previous years see Stuff we figured out about …

Every era is shaped by its miracle material. Steel forged the Gilded Age. Semiconductors switched on the Digital Age. Now AI has arrived as infinite minds. If history teaches us anything, those who master the material define the era.

Start with a component library: Radix or Base UI.

We rebuilt every component for Base UI, keeping the same abstraction. They are fully compatible with your existing components, even those pulled from remote registries.

When you add components, we auto-detect…

Last year, in the article “5 tips to effectively optimize INP in React,” we focused on what developers often underestimate when optimizing React.

React is not automatically fast, and long JavaScript tasks can arise from perfectly common constructs. A larger…

Base64 is a binary-to-text encoding scheme that converts arbitrary binary data (like images, files, or any sequence of bytes) into a safe, printable ASCII string using a 64-character alphabet (A–Z, a–z, 0–9, +, /). Browsers use it in JavaScript to embedding…
