Creating the Internet of Things with JavaScript - Fluent Conf
This document discusses how JavaScript is well-suited for creating applications for the Internet of Things. It notes that batteries and network bandwidth have improved over time based on various laws, but batteries have improved more slowly. It advocates for an event-driven programming model where devices only transmit interesting event data rather than a continuous stream of sensor data. This reduces power consumption and data transmission costs. JavaScript is highlighted as an easy way to create dynamic IoT applications that can be updated over the network. Example IoT development platforms that use JavaScript like BeagleBone and NinjaBlocks are also mentioned.
