Pros: Flexible delegation; memory-efficient shared methods on prototype. Cons: Prototype pollution if __proto__ mishandled; instanceof checks break across realms.
Detailed answer
Trade-offs for Prototype Chain and Inheritance: Pros: Flexible delegation; memory-efficient shared methods on prototype.
