 Bun provides a handful of module-specific utilities on the [`import.meta`](/docs/api/import-meta) object. Use `import.meta.main` to check if the current file is the entrypoint of the current process.
 
 ```ts#index.ts
-if(import.meta.main){
+if (import.meta.main) {
   // this file is directly executed with `bun run`
-}else{
+} else {
   // this file is being imported by another file
 }
