 The result conforms to the `SuccessOrFail` type returned by `context.evalCode`, so you can use `context.unwrapResult(context.getPromiseState(promiseHandle))` to assert a promise is settled successfully and retrieve its value. Calling `context.unwrapResult` on a pending or rejected promise will throw an error.
 
 ```typescript
-const promiseHandle = context.evalCode(`Promise.resolve(42)`);
-const resultHandle = context.unwrapResult(
-  context.getPromiseState(promiseHandle)
-);
-context.getNumber(resultHandle) === 42; // true
-resultHandle.dispose();
-promiseHandle.dispose();
