# regexp/no-obscure-range

disallow obscure character ranges

  • ⚙️ This rule is included in "plugin:regexp/recommended".

# 📖 Rule Details

The character range operator (the - inside character classes) can easily be misused (mostly unintentionally) to construct non-obvious character class. This rule will disallow all non-obvious uses of the character range operator.

{
  "regexp/no-obscure-range": ["error",
    {
      "allowed": "alphanumeric" // or "all" or [...]
    }
