eslint/no-irregular-whitespace Correctness

✅ This rule is turned on by default.

What it does

Disallows the use of irregular whitespace characters in the code.

Why is this bad?

Irregular whitespace characters are invisible to most editors and can cause unexpected behavior, making code harder to debug and maintain. They can also cause issues with code formatting and parsing.

Examples

Examples of incorrect code for this rule:

// Contains irregular whitespace characters (invisible)
function example() {
  var foo = "bar"; // irregular whitespace before 'bar'
}

Examples of correct code for this rule:

function example() {
  var foo = 'bar'; // regular spaces only
}


## How to use

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

::: code-group

```bash [CLI]
oxlint --deny no-irregular-whitespace

Config (.oxlintrc.json)

{
  "rules": {
    "no-irregular-whitespace": "error"
  }
}
