eslint/no-void Restriction

🚧 An auto-fix is still under development.

Disallow void operators.

Why is this bad

The void operator is often used to obtain the undefined primitive value, but it is unnecessary. You can use undefined directly instead.

Examples of incorrect code for this rule:

void 0;
var foo = void 0;

Examples of correct code for this rule:

"var foo = bar()";
"foo.void()";
"foo.void = bar";

How to use

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

CLIConfig (.oxlintrc.json)

bash

oxlint --deny no-void

json

{
  "rules": {
    "no-void": "error"
  }
}
