# Disallow Use of Chained Assignment Expressions (no-multi-assign)

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

```js
(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.
```
