# Enforce "for" loop update clause moving the counter in the right direction. (for-direction)

## Rule Details

A `for` loop with a stop condition that can never be reached, such as one with a counter that moves in the wrong direction, will run infinitely. While there are occasions when an infinite loop is intended, the convention is to construct such loops as `while` loops. More typically, an infinite for loop is a bug.

Examples of **incorrect** code for this rule:

```js
/*eslint for-direction: "error"*/
for (var i = 0; i < 10; i--) {
}

for (var i = 10; i >= 0; i++) {
}
```

Examples of **correct** code for this rule:

```js
/*eslint for-direction: "error"*/
for (var i = 0; i < 10; i++) {
}
```
