### What it does

This rule warns when the `matchAll` method is called with a regular expression that does
not have the global flag (g).

### Why is this bad?

When called with a regular expression, the `matchAll` method requires the global flag (g).
Otherwise, it throws a `TypeError` at runtime instead of returning an iterator.

### Examples

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

```javascript
text.matchAll(/pattern/);
```

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

```javascript
text.matchAll(/pattern/g);
```

## How to use

## Version
