Disallows control characters in regular expressions.
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:
/*eslint no-control-regex: "error"*/
var pattern1 = /\x1f/;
var pattern2 = new RegExp("\x1f");
Examples of correct code for this rule:
/*eslint no-control-regex: "error"*/
var pattern1 = /\x20/;
var pattern2 = new RegExp("\x20");
If you need to use control character pattern matching, then you should turn this rule off.
