Hello @DenisTRUFFAUT,
I think this has been proposed by @theScottyJam here.
EDIT: We already use : instead of as for renaming.
There is also an inline, rather verbose way to do this using IIFE, destructuring + construction.
const b = (({ id, name, age }) => { id, name, age })(a);
This would be slightly better if your object names are longer than a and b.
Thank you
.
