Javascript has many shorthands for assignment operator like `??=`, `&&=`, `+=` and others. Also objects can be initialized using literal notation:` const a = 5; const obj = { a };`. So how about a shorthand for property assignment which based on them?  
It's syntax is very simple. Instead of:  
`obj.prop = prop`  
We just write  
`obj .= prop`  
The rule is very simple. Shorthand is allowed on object property assignment to variable when property and variable names are equal. The syntax is intuitive and clear, IMO  
So, what do you think? Please share your opinion.

I disagree on that particular point.

In general, `obj <OP>= val` is roughly equivalent to `obj = obj <OP> val`; e.g.

- `obj += val` is equivalent to `obj = obj + val`, except that `obj` is evaluated only once;

- `obj ??= val` is equivalent to `obj = obj ?? val`, except that assignment may be skipped per short-circuiting semantics.

So I expect `obj .= prop` be equivalent to `obj = obj.prop`, which is completely different from you mean.

And this potential point of confusion makes me feel this is probably not a good idea to add.
