Wtf does this do

Uniq is a small JavaScript utility that removes duplicate values from a list (array). Instead of manually filtering through your data to find and eliminate copies, you pass an array to this tool and it returns a clean version with only unique items kept. Think of it like cleaning up a contact list, if you've accidentally imported the same person's email address twice, uniq strips out that duplicate so you're left with one clean entry per contact. It's a straightforward, focused piece of code that solves one problem well: taking messy data with repeats and making it tidy. You'd use this whenever you're working with JavaScript and need to deduplicate data. Common scenarios include cleaning up user submissions, removing repeated items from a CSV import, or ensuring a list of IDs contains no accidental doubles. Instead of writing your own logic to check for duplicates and filter them out, you can just call this utility and let it handle the work. The project is intentionally minimal, it does one thing and does it reliably. The README doesn't go into extensive detail about configuration or advanced options, suggesting this is meant to be a lightweight, straightforward solution you can drop into your code and use immediately without much setup or learning curve.
