Add code comments to the code to aid understanding.

I'm trying to wrap my head around some of the details of the signalk implementation and adding comments seemed like the most efficient way to do this. I figured others would benefit from the work.

There's some very light refactoring in here where it simplified the explanation.

Little bit of refactoring to simplify the flow.

- No need for an else branch when the if branch ends with a return
- path length is compared to 0 at the beginning of the function, no need
to check it's not 0 at the end
s/mmsiPrefixLenght/mmsiPrefixLength/
findContext() is really doing two jobs, so renamed to describe what else
it's doing.  It's probably best to split into multiple functions, but
this seemed simplest for now.

All in all a really nice job! I've done the same a few times in open source projects, documenting how an algorithm works just to wrap my head around it. Nice to be on the receiving end!

Would you mind addressing my minor comments?

parts.reduce((cursor, part) => {
if(typeof cursor[part] === 'undefined') {
return cursor[part] = {}
}
return cursor[part]
}, this.sources)

// Uh, shouldn't something be done with the result of the reduce? What if
// the pointed to value isn't found?

You already documented what this does: creating elements as needed, using reduce cursor as a temp variable.

I'm still confused. All this does is create elements, it doesn't actually update anything. Notice that context and timestamp aren't referenced in the body of the method. (Which means my comment is wrong, it's descending into this.sources, not context.)

Ok, so

  • it is handling this.sources and context is not needed nor used here, should be removed
  • it is not updating timestamp, which it should be doing, so a bug - add a FIXME comment in this documentation PR?
  • your comment about descending into sources of the context is not correct, so to get this PR merged please remove that
