when, where to use "reset or clear"?

[thearabbit]

I am a new for this package.
But don't understand when, where to use "reset or clear"?

// In docs
var subs = new SubsManager(); // use in router such as `Flow Router`

// later in some other place
subs.clear()/.reset(); // Where and When??? 

I think that we can't us subs in global, because it declare with var.
Please help me.

Neither one is working for mine.
