## Implementation

```javascript
function stripAnsi(text) { return text.replace(/[\u001b\u009b][[()#;?]*(?:[0-9]{1,4}(?:;[0-9]{0,4})*)?[0-9A-ORZcf-nqry=><]/g, ''); }
```

## Input

```json
"\u001b[31mError\u001b[0m"
```

## Expected output

```json
"Error"
```

## Edge case

Input:
```json
"plain"
```
Output:
```json
"plain"
```

## Limits

- Covers SGR colors and common CSI sequences, not every operating-system command sequence.

The lab validates types and size before calling this function. Add equivalent validation at your own trust boundary.
