### Status of Required WebAssembly Features
The following table shows the status of future WebAssembly features required by JWebAssembly in nightly builds in various implementations. These features are already used by the trunk version of JWebAssembly.
| Feature | V8 | SpiderMonkey | WABT |
| ----------------------- | ------ | ------------ | ------ |
| [floar-to-int][1] | yes | yes | yes |
| [Sign-extension][2] | yes | yes | yes |
| [Multi-value][3] | yes | - | yes |
| [Reference Types][4] | yes | yes | - |
| [Garbage collection][5] | - | partly | - |
| [Exceptions][6] | partly | - | partly |
- For V8 it based on the [V8 - node.js integrations builds](https://ci.chromium.org/p/v8/builders/luci.v8.ci/V8%20Linux64%20-%20node.js%20integration).
- For SpiderMonkey it based on the nightly build of [jsshell](https://archive.mozilla.org/pub/firefox/nightly/latest-mozilla-central/).
- For WABT it based on [libwabt.js](https://github.com/WebAssembly/wabt/blob/master/demo/libwabt.js) via node module wabt@nightly.
To use it also some flags and switches are needed.
