About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
In JavaScript, every function used as a constructor automatically receives a prototype object, which serves as the shared source for properties and methods among all instances created by that constructor.
In simple terms: Constructor functions inherit a default prototype.
Prototype enables shared behavior across instances.
