+## Style Guide
+
+- Keep things in one function unless composable or reusable
+- Avoid unnecessary destructuring. Instead of `const { a, b } = obj`, use `obj.a` and `obj.b` to preserve context
+- Avoid `try`/`catch` where possible
+- Avoid using the `any` type
+- Prefer single word variable names where possible
+- Use Bun APIs when possible, like `Bun.file()`
+
+# Avoid let statements
+
+We don't like `let` statements, especially combined with if/else statements.
+Prefer `const`.
+
+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 using an `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
+```
