$state.go(to [,toParams] [,options])
Returns a Promise representing the state of the transition.
Convenience method for transitioning to a new state. $state.go calls $state.transitionTo internally but automatically sets options to { location: true,inherit: true,relative: $state.$current,notify: true }. This allows you to easily use an absolute or relative to path and specify only the parameters you’d like to update (while letting unspecified parameters inherit from the current state).
$state.transitionTo(to,toParams [,options])
Returns a Promise representing the state of the transition.
Low-level method for transitioning to a new state. $state.go() uses transitionTo internally. $state.go() is recommended in most situations.
