Disallow Extending Native Objects (no-extend-native)

Prevent changing the behavior of built-in JavaScript objects, such as Object or Array, by modifying their prototypes. This is a standard rule built into ESLint.

For complete details about this rule, including examples, see the corresponding ESLint documentation, Disallow Extending of Native Objects (no-extend-native).
