Hi all,
I often come across a situation where I wish to extend an object
(usually an argument for an API request) if a particular condition is
satisfied, such as the presence of a function parameter. Currently the
only way to do this is by assigning the object to a variable, checking
the condition using an `if` statement and then extending the object. I
am proposing the inclusion of an operator that allows a property to be
included, subject to a particular condition, inside the object
definition.
You can already do
```js
let obj = Object.assign({
…
}, cond ? { prop: value } : null);
```
Or depending on your condition, also just `cond && { prop: value }`.
The object spread proposal will achieve the same, without the need for
any extra operator.
