Mô tả
I have this code:
```
assert('Need profile data', this.args.window.profile?.data);
```
When optional chaining is *not* transpiled, things work fine. The line above is transformed to:
```
(true && !(this.args.window.profile?.data) && (0, _debug.assert)('Need profile data', this.args.window.profile?.data));
```
However some automated dependency updates including most Babel stuff changed behavior, in that optional chaining is now transpiled, I believe due to some bug in Chrome, see https://github.com/babel/babel/issues/13145.
But now the transform yields this broken code:
```
var _this$args$window$pro;
(true && !(_this$args$window$pro.data) && (0, _debug.assert)('Need profile data', (_this$args$window$pro = this.args.window.profile) === null || _this$args$window$pro === void 0 ? void 0 : _this$args$window$pro.data));
```
Which throws with `Cannot read properties of undefined (reading 'data')` as at the time the `!(_this$args$window$pro.data)` expression is evaluated `_this$args$window$pro` is still undefined!
