Is there a way to clear entire context? I've found two ways to do that:
1. Use Switch -\> delete.flow but it needs to be specified unless there is some way to delete all?
2. Use context.set() = undefined but it doesn't seem to work at all, I'm using it like this:

Not out of the box. You would need to get the keys and iterate them, setting each one to `undefined`
```auto
const keys = flow.keys()
for (let index = 0; index < keys.length; index++) {
const key = keys[index];
flow.set(key, undefined)
}
```

### BETTER MANAGEMENT of context:
Store all your context variables in a single object, then you can just delete that 1 single object.

Thank you very much, this works perfectly

Could this also be used to reset all context context instead of flow context?
I tried
```auto
const flowkeys = flow.keys()
for (let index = 0; index < flowkeys.length; index++) {
const flowkey = flowkeys[index];
flow.set(flowkey, undefined)
}
const contextkeys = context.keys()
for (let index = 0; index < contextkeys.length; index++) {
const contextkey = contextkeys[index];
context.set(contextkey, undefined)
}
return msg
```
but the context context were not deleted. I would imagine maybe because they are not available outside of the respective nodes.

It would only work for the own nodes context. So for every function you have context, you would need to run that code.
You could setup a conditional section of code e.g.
```auto
if(msg.topic === 'clear') {
// clear context code
return
}
// other code here
```
In each of the functions.
Or, better, set up a link call subroutine and send the `context` to clear to a common "clear context" subroutine. So you don't have code duplication.
