eslint/no-proto Restriction

🚧 An auto-fix is still under development.

What it does

Disallow the use of the __proto__ property.

Why is this bad?

The __proto__ property has been deprecated as of ECMAScript 3.1 and shouldn’t be used in new code. Use Object.getPrototypeOf and Object.setPrototypeOf instead.

For more information, see the MDN documentation.

Examples

Examples of incorrect code for this rule:

/*eslint no-proto: "error"*/

var a = obj.__proto__;

var a = obj["__proto__"];

obj.__proto__ = b;

obj["__proto__"] = b;

How to use

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

CLI

oxlint --deny no-proto

Config (.oxlintrc.json)

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