In the JS documentation (Template Content with Vanilla JavaScript - Prismic), the next_page and prev_page values are described as returning "The next/prev page number in the pagination". However, when I console out these values I get a URL to the next/prev set of results not the page number.
console.log(response['next_page'])
I'm not sure if the issue here is with the documentation or the result returned but my preference here would definitely be to get the next/prev page number as an integer not a URL. At the moment I work around this manually using the page number the user has given and the total_pages value from the response but ideally I'd like to be able to use the relevant response fields.
