Note: This release is in preview. Features described here don’t become generally available until the latest general availability date that Salesforce announces for this release. Before then, and where features are noted as beta, pilot, or developer preview, we can’t guarantee general availability within any particular time frame or at all. Make your purchase decisions only on the basis of generally available products and features.

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).
