Alice comes online and does
`var todo = gun.get('todo')`
However she is the first peer, objectively, to be around.
Therefore, very quickly her query returns empty. So when she
`todo.put({first: "buy groceries"}).key('todo')`
the put has to generate a soul and GUN is instructed to associate 'todo' with that soul.
A few hours later, Bob comes online and does
`var todo = gun.get('todo')`
and thankfully he was connected to Alice so he gets her soul and node. So when he
`todo.put({last: "sell leftovers"}).key('todo')`
this was the expected and intended result, producing the following graph:
```{
'ASDF': {
_: {'#': 'ASDF', '>': {
first: 1,
last: 2
}},
first: "buy groceries",
last: "sell leftovers"
}
}```
For purposes of clarity, we are using states as if they were linearizable (this is not actually the case though).
Then Carl comes online and tries to
`var todo = gun.get('todo')`
But since he is not connected to Alice or Bob, gets an empty result.
Carl does nothing with it, meaning no mutation, no soul, no generation.
Then Dave comes online and does the same as everyone else:
`var todo = gun.get('todo')`
But Dave is only connected to Carl as a peer, therefore his get is empty. Like Alice, he then
`todo.put({remember: "eat food!", last: "no leftovers!"}).key('todo')`
Which unfortunately causes a new soul to be generated. Meanwhile, everybody then does the following:
`todo.on(function(val){ console.log(val) })`
Alice and Bob immediately get:
```{
_: {'#': 'ASDF', '>': {
first: 1,
last: 2
}},
first: "buy groceries",
last: "sell leftovers"
}```
But Carl and Dave immediately get:
```{
_: {'#': 'FDSA', '>': {
remember: 3,
last: 3
}},
remember: "eat food!",
last: "no leftovers!"
}```
However, a few hours later everybody gets connected. This is the graph everyone then has:
```{
'ASDF': {
_: {'#': 'ASDF', '>': {
first: 1,
last: 2
}},
first: "buy groceries",
last: "sell leftovers"
},
'FDSA': {
_: {'#': 'FDSA', '>': {
remember: 3,
last: 3
}},
remember: "eat food!",
last: "no leftovers!"
}
}```
But their `on` function triggers again, with the following `val` locally for everyone:
```{
first: "buy groceries",
remember: "eat food!",
last: "no leftovers!"
}```
GUN merges all the nodes with matching keys into a temporary in-memory object.
This way it is safe to get empty results and still put data into it,
Everyone will see a unified view of the data when they do get connected, as intended.
This solves the null, singular, and plural problems for get all together.
However, if we intentionally do not want to see a potentially conflicting unified view, any peer can:
`var todos = gun.all('todo')`
And have the discrete data via:
`todos.map(function(todo, soul){ console.log(todo) })`
Which would currently get called twice, with the distinct nodes of 'ASDF' and 'FDSA'.
The only thing that this does not address is how write operations (put/key) would effect `get` nodes.
However, I feel like finding the answer to that question will be much easier than trying to solve `get` in any other way.
