 By default, **only the first argument is considered** and it only works with [primitives](https://developer.mozilla.org/en-US/docs/Glossary/Primitive). If you need to cache multiple arguments or cache `object`s *by value*, have a look at alternative [caching strategies](#caching-strategy) below.

 Better yet, if your function’s arguments are compatible with `WeakMap`, you should use [`deep-weak-map`](https://github.com/futpib/deep-weak-map) instead of `many-keys-map`. This will help avoid memory leaks.

+### mem.decorator(options)
+
+Returns a [decorator](https://github.com/tc39/proposal-decorators) to memoize class methods or static class methods.
+
+Notes:
+
+- Only class methods and getters/setters can be memoized, not regular functions (they aren't part of the proposal);
+- Only [TypeScript’s decorators](https://www.typescriptlang.org/docs/handbook/decorators.html#parameter-decorators) are supported, not [Babel’s](https://babeljs.io/docs/en/babel-plugin-proposal-decorators), which use a different version of the proposal;
+- Being an experimental feature, they need to be enabled with `--experimentalDecorators`; follow TypeScript’s docs.
