# Disallow Use of \__proto\_\_ (no-proto)

Prevents using the obsolete `__proto__` property, which was deprecated in ECMAScript 3.1. Use `Object.getPrototypeOf()` instead. This is a standard rule built into ESLint.

For complete details about this rule, including examples, see the corresponding ESLint documentation, [Disallow Use of \__proto\_\_ (no-proto)](https://eslint.org/docs/rules/no-proto).
