`a ||= b` looks like an in-place logical or, like `+=`.
`a = a || b` would have very different semantics to that which you propose.
In Python this would be written:
```python
if a in [1, 2, 3, 5]:
# stuff
```
In JS we have similar but slightly less semantic:
```js
if ([1, 2, 3, 5].indexOf(a) > -1) {
// stuff
}
```
