• Component: JavaScriptCore
• Status: RESOLVED WORKSFORME

A short html snippet to reproduce the issue

Consider the following code: 

async function async_test(prop1) {
    var {prop1, prop2} = prop1;
    console.log(prop1)
  }

async_test({prop1: 'async_param', prop2: 2});

## Expected output: "async_param"
## Actual output: Unhandled Promise Rejection: TypeError: Right side of assignment cannot be destructured

Additional note: The same scenario works as expected in a non async context.

Expected output can be reproduced in Chrome, Firefox, Edge

csongor, This seems to be working for me in STP 190.
Do not hesitate to chime in if you think I have closed too soon.

I can confirm that it works in Technology Preview 190. Looking forward to be included in the main build too.
