eslint/no-negated-condition Pedantic

🚧 An auto-fix is still under development.

What it does

Disallow negated conditions.

Why is this bad?

Negated conditions are more difficult to understand. Code can be made more readable by inverting the condition.

Example

Examples of incorrect code for this rule:

if (!a) {
  doSomethingC();
} else {
  doSomethingB();
}

!a ? doSomethingC() : doSomethingB();

Examples of correct code for this rule:

if (a) {
  doSomethingB();
} else {
  doSomethingC();
}

a ? doSomethingB() : doSomethingC();

How to use

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

CLI

oxlint --deny no-negated-condition

Config (.oxlintrc.json)

{
  "rules": {
    "no-negated-condition": "error"
  }
}
