jsvu

# JSVU (JavaScript engine Version Updater) Use `jsvu` to install and test across multiple JavaScript engines (e.g., v8, spidermonkey, javascriptcore, chakra). ## Installation and Setup For non-interactive installation and updating of specific engines on Linux, run: ```bash npx jsvu --os=linux64 --engines=v8,spidermonkey,javascriptcore ``` You can customize the `--engines` flag with the engines you wish to test (e.g., `v8,v8-debug,spidermonkey,javascriptcore,graaljs`). ## Running Engines Once installed, the engines are available in `~/.jsvu/bin/`. You can run them directly: ```bash ~/.jsvu/bin/v8 my_test.js ~/.jsvu/bin/spidermonkey my_test.js ~/.jsvu/bin/javascriptcore my_test.js ``` This allows you to easily cross-reference behaviors and bugs against other major JS engines.
