error-cause
An ES-spec-compliant shim/polyfill/replacement for the `.cause` property on all Error types that works as far down as ES3
top-level await feature for ES modules
The top-level await feature for ES modules makes it easy to use await in CLI scripts (e.g., with .mjs sources and zx), and for dynamic imports and data loading. It extends the await functionality into the module loader, which means that dependent modules will wait for async modules (with top-level await) to be loaded.
The current browser support for the error clause feature is limited (Dec 2021 usage: ~70%), and it is not available in Node.js yet. You can use the error cause polyfill to start using the feature today, even in JS environments where it is not supported.
The browser support for the RegExp match indices feature is currently limited (Dec 2021 usage: ~80%). In Node.js, you can activate the feature with the --harmony-regexp-match-indices flag, but it is disabled by default. You can use the RegExp match indices polyfill in the meantime.
