There is a Hackaday page that mentions that “the LoShark’s primary strength is its ability to execute JavaScript (ES2015) through our runtime, Resonance. It’s still in alpha state, and it will be open sourced with a free software license soon later. You can join our Discord for alpha testing at this moment. This feature enables users to program specific tasks, serving as a powerful tool for LoRa debugging, such as capturing packets and sending LoRa messages either manually or programmatically, at minimal delay”
