# 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.
