And it is so easy for Zephyr to do that. moddable.com/blog/zephyr-3/

👩🏽‍💻 Every JavaScript developer knows that they should minimize blocking. 🤔 Unfortunately, the usual remedy can actually reduce perceived performance. 🧑‍🎓 Our blog goes in-depth on three approaches so you'll understand the tradeoffs. moddable.com/blog/asynchrono…

Grok made a thing. @moddabletech Moddable Display 2 It couldn't use Bender ©, so it made its own. (It's only Wednesday.)

Web Serial was invented so PCs could talk to microcontrollers. Now microcontrollers can talk back using Web Serial, thanks to Moddable's new Web Streams.

Web Streams are part of the Web’s foundation. But they’ve been out of reach for Embedded JavaScript. Until now. 🔥Moddable found a way to run streams efficiently on microcontrollers.🎉 Our blog tells the story of this huge step forward for embedded devs. moddable.com/blog/web-stream…

Our Guides are a new kind of documentation, designed for Embedded JavaScript developers and their LLMs. Their code-first approach pairs small code snippets paired with concise explanations. They show how to perform common tasks simply. moddable.com/blog/guides/

Exactly! AGENTS.md strongly recommends to use Guides as the starting point for API documentation. Seems to be enough to get the LLMs to notice, but improvements are always welcome.

Grok one-shotted the JavaScript driver for this Alphanumeric display run over Qwiic (I2C). It's shown running on the qtpys3, but since it is written to the ECMA-419 spec, it can run on nRF52840, Pico, other ESP32 variants without change. Thanks @grok @moddabletech

At Moddable, we believe industry standards can transform software development. Our latest blog post shows how ECMA-419 simplifies Bluetooth Low Energy development by a couple orders of magnitude and reduces DNS-SD integration to a few lines of JavaScript. moddable.com/blog/ecma-4/
