🔥 #Laravel Tip: Eloquent's 'whereExists' method is useful, but it relies on sub queries. A more efficient way to run the same query is an advanced inner join.

A nice SQL trick - you can update a table from another table using joins 👀 Just added a `deleted_at` column to a table and want it populated by one of it's relations, just do an update statement and join them. One simple, yet powerful query 🤯
