As a rule of thumb _The name of the reactive variable must appear on the left side of the equals to react to assignments._
For example, this case wouldn't work:
A simple rule of thumb: the name of the updated variable must appear on the left hand side of the assignment. For example this...
```js
const childRef = obj.foo;
childRef.bar = "new value";
const foo = obj.foo;
foo.bar = 'baz';
```
And to make it work it would be needed to force an update to object with `obj = obj`.
...won't update references to `obj.foo.bar`, unless you follow it up with `obj = obj`.
