Is there UserService analogy in js?

[Igor Slinko]

Or should I use REST to check if pageState.getCurrentUser() user is admin?

[Igor Slinko · Accepted solution]

pageState.getCurrentUser().attributes.isAdmin

There's no JS equivalent for UserService. Usually you hide the admin features from non-admins when you load the initial page, and REST endpoints will return error codes when you try to use them as a non-admin.
