Using Golang and TinyGo’s BLE library, learn how to connect to Bluetooth Low Energy devices. This introduction uses the AOJ-20A thermometer from Lepu but using other BLE enabled devices will work in a similar way.

Imagine you are working on the next big thing that runs in the browser, and it requires some heavy-duty code, which need to run fast and efficient. You remember that your friend Jack told you about WebAssembly (Wasm), which supposedly runs faster than JavaScript (JS), so you decide to check it out. The thing you are working on involves sorting large amounts of data, so you test a pure JS implementation first.
