Under the Authentication section on https://api.stackexchange.com/docs/js-lib, there are a few typos (emphasis mine):
scope (optional) – an array of scopes to request during authentication, valid scopes are in the authentication documentaiton.
documentaiton => documentation
If networkUsers was not passed to SE.authenticate networkUsers will not bet set, if set it is an array of network_user objects.
not bet set => not be set
Under the Errors section:
Note that the user reject an application is conceptually an error.
the user reject => the user rejecting
Under the Unregistered Users section:
We want to provide this data, but we also want to be able to shut down scrappers who aren't following our attribution terms
scrappers => scrapers
Also, this isn't a typo, but I think this could be rephrased:
Once you have authenticated a user once
the duplicate once doesn't sound right!
As @JF suggests, it could be:
After you have authenticated a user once
