 The emit format of each file is determined by the [detected module format](#module-format-detection) of each file. ESM emit is similar to [`--module esnext`](#es2015-es2020-es2022-esnext), but has a special transformation for `import x = require("...")`, which is not allowed in `--module esnext`:
 
 ```ts
+// @Filename: main.ts
 import x = require("mod");
