Programming should be fun and easy, right? Developers should spend their time in creating innovative solutions, not on board issues and tools setup. JavaScript is one of the most popular scripting languages. It is easy to learn and fast to develop with. With new Zephyr JavaScript Runtime developers can use JavaScript to create Zephyr applications. Based on JerryScript, the Node.js like Zephyr JavaScript Runtime provides access to Zephyr APIs (via bindings) including BLE, GPIO, PWM, OCF and many more in the future. JavaScript development on Zephyr is also fast, you don’t need to compile, link, flash or reboot, just copy and run. Believe or not, you can do all this with Arduino 101 which contains only 384K ROM and 80 K RAM. Join this presentation to learn more, and how to contribute. Yes, it is an open source project!
