 During transformation, file formats are automatically resolved, and in most cases, no additional configuration is required.
 
-The default module environment for generated files is `esm`, which means output files will have a `.mjs` extension unless otherwise specified. For TypeScript declarations, the corresponding extension will be `.d.mts`.
+The default module environment for generated files is `esm`, which means output files will have a `.js` extension unless otherwise specified. For TypeScript declarations, the corresponding extension will be `.d.ts`.
 
 Formats can also be explicitly specified for each entry, if needed.
 
 ### Inputs
 
 Default transformation behavior for all `chunk` entries:
 
-- `./srcDir/file.js` → `./outDir/file.mjs`
-- `./srcDir/file.mjs` → `./outDir/file.mjs`
+- `./srcDir/file.js` → `./outDir/file.js`
+- `./srcDir/file.mjs` → `./outDir/file.js`
 - `./srcDir/file.cjs` → `./outDir/file.cjs`
-- `./srcDir/file.ts` → `./outDir/file.mjs`
-- `./srcDir/file.mts` → `./outDir/file.mjs`
+- `./srcDir/file.ts` → `./outDir/file.js`
+- `./srcDir/file.mts` → `./outDir/file.js`
 - `./srcDir/file.cts` → `./outDir/file.cjs`
 
 ### Declarations
 
 Default transformation behavior for all `dts` entries:
 
-- `./srcDir/file.ts` → `./outDir/file.d.mts`
+- `./srcDir/file.ts` → `./outDir/file.d.ts`
