 * All methods are type-safe.
 * Everything is module, with no `window` and `global.d.ts`.
 * By default, the [serialize-error](https://www.npmjs.com/package/serialize-error) library is used to serialize error objects, so you don't have to worry about error handling. You can also customize the error handler.
-* `global.d.ts` is not required.
+* Provide some optional security mechanisms to enhance security.
 
 **Even if you don't use TypeScript, you can use this library, which can help alleviate the burden of using IPC.**
