 ## Style Guide
 
-- Try to keep things in one function unless composable or reusable
-- AVOID unnecessary destructuring of variables. instead of doing `const { a, b }
-= obj` just reference it as obj.a and obj.b. this preserves context
-- AVOID `try`/`catch` where possible
-- AVOID using `any` type
-- PREFER single word variable names where possible
-- Use as many bun apis as possible like Bun.file()
