JerryScript is a lightweight JavaScript engine designed to bring the success of JavaScript to small IoT devices like lamps, thermometers, switches and sensors. This class of devices tends to use resource-constrained microcontrollers which are too small to fit a large JavaScript engine like V8 or JavaScriptCore. JerryScript is heavily optimized for low memory consumption and runs on platforms with less than 64KB of RAM and less than 200KB of flash memory. Despite the low footprint, JerryScript is a full-featured JavaScript engine implementing the entire ECMAScript 5.1 standard. It is actively used in production and already runs on more than one million smartwatches! JerryScript is an open source project and has been released under the Apache License 2.0. The talk will include a demo showing JavaScript code executing on top of JerryScript on a resource-constrained microcontroller.

LLVM has been around for over a decade and is more popular than ever. Its combination of an easy to use API coupled with high quality documentation has lowered the barrier to compiler development significantly. This has led to a strong adoption of LLVM in many different areas and as a result we can see a wide range of projects using LLVM today. Projects using LLVM cover a large spectrum of domains, ranging from classic C/C++ toolchains to code obfuscation engines and binary translators. The vast number of different projects based on LLVM and the fact that new projects are appearing constantly makes it increasingly hard to keep track of all of them. This talk attempts to summarize the current landscape of projects which are using LLVM in one way or another. The focus of this talk is on projects using LLVM rather than the LLVM compiler infrastructure itself.

IoT.js is a platform for IoT applications written in JavaScript. With IoT.js developers can create IoT services that communicate with each other and the outside world. IoT.js is a lightweight version of Node.js and designed to bring the success of Node.js to small IoT devices like lamps, thermometers, switches and sensors. This class of devices tends to use resource-constrained microcontrollers which are too small to fit a full Node.js stack. In order to meet those constraints, IoT.js runs on top of JerryScript which is a lightweight JavaScript engine running on platforms with less than 64KB of RAM and less than 200KB of flash memory. Despite the low footprint, JerryScript is a full-featured JavaScript engine implementing the entire ECMAScript 5.1 standard. Both IoT.js and JerryScript are open source projects released under the Apache License. The talk will include a demo running a Node.js module with IoT.js on a resource-constrained microcontroller.
