 - 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 `else` statements
 - AVOID using `any` type
-- AVOID `let` statements
 - PREFER single word variable names where possible
 - Use as many bun apis as possible like Bun.file()

+# Avoid let statements
+
+we don't like let statements, especially combined with if/else statements.
+prefer const
+
+This is bad:
+
+Good:
+
+```ts
+const foo = condition ? 1 : 2
+```
+
+Bad:
+
+```ts
+let foo
+
+if (condition) foo = 1
+else foo = 2
+```
+
+# Avoid else statements
+
+Prefer early returns or even using `iife` to avoid else statements
+
+Good:
+
+```ts
+function foo() {
+  if (condition) return 1
+  return 2
+}
+```
+
+Bad:
+
+```ts
+function foo() {
+  if (condition) return 1
+  else return 2
+}
+```
+
+# Prefer single word naming
+
+Try your best to find a single word name for your variables, functions, etc.
+Only use multiple words if you cannot.
+
+Good:
+
+```ts
+const foo = 1
+const bar = 2
+const baz = 3
+```
+
+Bad:
+
+```ts
+const fooBar = 1
+const barBaz = 2
+const bazFoo = 3
+```
