`servant-client-ghcjs` is much like `servant-client`, as both packages allow you to generate functions that query the endpoints of your servant API. Both packages should feel the same in usage. The big difference lies in how they perform the actual requests. `servant-client` (indirectly) uses your operating system's socket mechanisms, whereas `servant-client-ghcjs` uses your browser's [XHR](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/Using_XMLHttpRequest) mechanisms to send requests. `servant-client-ghcjs` is much like `servant-client`, as both packages allow you to generate functions that query the endpoints of your servant API.
