# disallow control characters in regular expressions (no-control-regex)
|
|
|
|
Control characters are special, invisible characters in the ASCII range 0-31. These characters are rarely used in JavaScript strings so a regular expression containing these characters is most likely a mistake.
|
|
|
|

|
This rule disallows control characters in regular expressions.
|

Examples of **incorrect** code for this rule:
|
|
|
|
```js
|
|
/*eslint no-control-regex: "error"*/
|
|
|
|
var pattern1 = /\x1f/;
|
|
var pattern2 = new RegExp("\x1f");
|
|
```
|

var pattern2 = new RegExp("\x20");
