[joyeecheung]

Remote participation worked today so should also work tomorrow. Zoom link is in https://docs.google.com/spreadsheets/d/1URn0hy4Mj-vSmZmZL8Z6_LPz5U5-WAAV-ueqVM4EVeY/edit?usp=sharing

Notes will be taken in https://hackmd.io/V3xtjlcrTIGsemPv8t-tKg - I put in the points to discuss there, planning to screen-share when we discuss

[charlieforward9]

To whom it may interest, I made a request here pertaining to my own task of reaching CJS/ESM interoperability and am seeking a brief review from someone more experienced in this scope.

Sorry that I could not attend as I was on a plane back home when this session happened. Thanks for publishing the notes. Was there also a recording of the zoom call that could be made available?

There was a recording being recorded on either @ovflowd 's Zoom cloud or his laptop locally. Not sure if he's got them or when it would be uploaded somewhere.

Let me add the recordings to the main issue 🙏
