}Promise.withResolvers is a static method that returns a new Promise along with its resolver functions, i.e. `const { promise, resolve, reject } = Promise.withResolvers()`. This is a standard version of a common helper function found in many JS libraries. Historically, some may know it as `defer` or `deferred`.

}The GC proposal adds efficient support for high-level managed languages to WebAssembly, via struct and array types that enable language compilers targeting Wasm to integrate with a garbage collector in the host VM. In Chrome, enabling this feature implies enabling Typed Function References, which allow function references to be stored in the aforementioned structs and arrays.
