Ruff, a special Internet of Things development platform designed to let devs easily develop code in JavaScript to run on a variety of devices. The aim of the platform is to make it easier to develop for IoT, using development tools that web devs either already know or can pick up easily. Ruff is a JavaScript runtime specialized in IoT development. Ruff makes embedded coding easy and more efficient by providing HAL, asynchronous I/O, event-driven programming. Ruff already has a big community of developers on its platform and has an extensive library of repositories with support for a range of devices, including sensors, cameras, and LEDs that are used frequently in IoT hardware. The platform also simplifies the process by eliminating the need for cross-compiling, and also removing any requirement for kernel development. Ruff's focus is all about making embedded development easy. In order to achieve this, Ruff not only allow developers to build with JavaScript, but also provide a platform Rap Registry for developers to share their drivers, frameworks, and libraries.
