WebCircuitPython is based on Python. Python is the fastest growing programming language. It's taught in schools and universities. It's a high-level programming language which means it's designed to be easier to read, write and maintain. It supports modules and packages which means it's easy to reuse your code for other projects. WebWe could use two byte arrays of size one but each MicroPython object is 16 bytes minimum due to the garbage collector. So, by sharing a byte array we keep it to the 16 byte minimum instead of 32 bytes. Each memoryview also costs 16 bytes minimum so we avoid them too. Another thing we could do is allocate the bytearray only when we need it.
