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.

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"
  }
}
