Control/filter database results through SQL queries rathen than using JS

[marisid]

• Better practice to limit database results when you query because of size and time required to make the query and then filter the results using JS.
• Instead of slicing here you could add LIMIT 8 at the end of your sql query.
• You could query the database for a specific user_id instead of filtering after you've got a big database set.
• Nice modularised structure of your JS code to get reviews and filter them though 👍
