I'm not hugely experienced in JS, and I know that you can't override the equality operator like you can in some other languages. But is there a way to do the switch without string comparison? Something like:
switch (true) {
case version.equals(BOLT_PROTOCOL_V1):
break;
case version.equals(BOLT_PROTOCOL_V5):
break;
default:
// default case
}
No idea if that would be preferable or idiomatic in JS, but to my C# brain it's preferable.

The selected bolt protocol version is represented as a floating point number in multiple places in the code. This is currently fine, but would cause the whole driver to explode if/when we introduce bolt 5.10 or 6.10.
