+# Converting Between JavaScript `Promise`s and Rust `Future`s
+
+The `wasm-bindgen-futures` crate bridges the gap between JavaScript `Promise`s
+and Rust `Future`s. Its `JsFuture` type provides conversion from a JavaScript
+`Promise` into a Rust `Future`, and its `future_to_promise` function converts a
+Rust `Future` into a JavaScript `Promise` and schedules it to be driven to
+completion.
