### Compatibility
Most modern JavaScript features that CoffeeScript supports can run natively in Node 7.6+, meaning that Node can run CoffeeScript’s output without any further processing required. Here are some notable exceptions:
* [JSX](#jsx) always requires transpilation.
* [Splats, a.k.a. object rest/spread syntax, for objects](https://coffeescript.org/#splats) are supported by Node 8.6+.
* The [regular expression `s` (dotall) flag](https://github.com/tc39/proposal-regexp-dotall-flag) is supported by Node 9+.
* [Async generator functions](https://github.com/tc39/proposal-async-iteration) are supported by Node 10+.
* [Modules](#modules) are supported by Node 12+ with `"type": "module"` in your project’s `package.json`.
This list may be incomplete, and excludes versions of Node that support newer features behind flags; please refer to [node.green](http://node.green/) for full details. You can [run the tests in your browser](test.html) to see what your browser supports. It is your responsibility to ensure that your runtime supports the modern features you use; or that you [transpile](#transpilation) your code. When in doubt, transpile.
For compatibility with other JavaScript frameworks and tools, see [Integrations](#integrations).
