Chaining the assignment of variables can lead to unexpected results and be difficult to read.

```js
a = b = c = d;
(function() {
const foo = bar = 0; // Did you mean `foo = bar == 0`?
bar = 1; // This will not fail since `bar` is not constant.
})();
console.log(bar); // This will output 1 since `bar` is not scoped.
```
