angularjs - What are the benefits of returning a function in templateURL? -

from https://github.com/angular-ui/ui-router/wiki

templateurl can function returns url. takes 1 preset parameter, stateparams, not injected.

$stateprovider.state('contacts', { templateurl: function ($stateparams){ homecoming '/partials/contacts.' + $stateparams.filterby + '.html'; } })

what of benefits of returning function in templateurl? sorry if bit vague. i'm trying wrap head around ui-router.

a "benefit" perhaps unusual way set it. adds way router dynamically decide template utilize given route, depending on $stateparams. alternative way of achieving similar utilize ngifs or ngswitchs in single template route.

which 1 utilize think own preference / think coding practice task in hand. if have 2 radically different, , long, templates, utilize function dynamic template url. if had short, or similar, templates, utilize ngif.

also, i've used ui-router few times now, , far never used function templateurl.
