I liked the ?? operator they added recently. But it would also be nice if there was an is null like operator that worked similar to NOT (!).
```javascript
!undefined // true
!null // true
!false // true
!'' // true
!0 // true
// something like
?undefined // true
?null // true
?false // false
?'' // false
?0 // false
```

You can just write `value == null` for that.

So you can, I didn't know that. Thanks!

I'm personally a bit uncomfortable using loose equality in Javascript.
Actually I think this idea would be a good feature to add to the language. When you look at the latest operators added to the language, we can see similar operators like `?.` , `??` , or `??=` , achieving the same purpose: easing comparisons with nullish values. This proposal would stay consistent with them.

However, I would treat the `?` operator in the same spirit than the `??` operator, instead of the `!` one.
Like:
```javascript
if (?myVar) {
// do something if myVar is defined (i.e. not undefined or null)
}
```
and the negation:
```javascript
if (!?myVar) {
// do something if myVar is nullish
}
```
