See it. Click it. Change it. Headless CMS and Visual Editing have had a looooong love-hate relationship. DatoCMS's new Visual Editing release takes a dual-approach that lets your editors click directly on any element in a live preview and jump straight to the right record and field in the CMS. OR. Get a native side-by-side editor to make changes in real time in the CMS with a slick full-screen editing mode.

As a dev, all you need to do is add 2 headers to your GraphQL requests and a lil <ContentLink /> component, and you're done 💁‍♀️ And just like that, you'll never hear "Where do I change this?!?!" ever again.

Interview question of the week

Last week, I had you do some symlink path resolution! Y'all did great Yassir, Andrew, Christian, Amine, Rob, Shreya, Jeremias, Trey, Donato, Thulasi, Toni, Lucy, Ten, Ross, Miguel, and David!

This week's question:
Given an integer n, return all unique combinations of Perrin numbers (up to and including the nth Perrin number) that sum to a target value k, where each Perrin number can be used at most once. Return the combinations sorted in ascending order.

Example:

> perrinCombinations(7, 12)
[[0,2,3,7],[0,5,7],[2,3,7],[5,7]]

> perrinCombinations(6, 5)
[[0,2,3],[0,5],[2,3],[5]]

(you can submit your answers by replying to this email with a link to your solution, or share on Bluesky, Twitter, LinkedIn, or Mastodon)
