eslint/no-empty-character-class Correctness

✅ This rule is turned on by default.

What it does

Disallow empty character classes in regular expressions

Why is this bad?

Because empty character classes in regular expressions do not match anything, they might be typing mistakes.

Example

var foo = /^abc[]/;

How to use

To enable this rule in the CLI or using the config file, you can use:

CLI

oxlint --deny no-empty-character-class

Config (.oxlintrc.json)

{
  "rules": {
    "no-empty-character-class": "error"
  }
}
