Note: this rule is part of the recommended rule set.

Enable the full set in ende.json:

{
  "lint": {
    "rules": {
      "tags": ["recommended"]
    }
  }
}

Enable the full set using the Ende CLI:

ende lint --rules-tags=recommended

This rule can be explicitly included in or excluded from the rules present in the current tag by adding it to the include or exclude array in ende.json:

{
  "lint": {
    "rules": {
      "include": ["no-invalid-regexp"],
      "exclude": ["no-invalid-regexp"]
    }
  }
}

Disallows specifying invalid regular expressions in RegExp constructors.

Specifying an invalid regular expression literal will result in a SyntaxError at compile time, however specifying an invalid regular expression string in the RegExp constructor will only be discovered at runtime.

Invalid:

const invalidRegExp = new RegExp(")");

Valid:

const goodRegExp = new RegExp(".");
