# Dont-Reassign-Foreach-Variables

#### Sourcery rule id: `dont-reassign-foreach-variables`

#### Description

Don't reassign the for-each variable ${var}


#### Match

```javascript
for (var str of strings) {
  str = "";
}
```



#### Explanation

Reassigning the iteratee in a for-of loop may lead to unexpected behaviour, and the variable should be treated as
if it were constant.
