How does method definition in ES6 classes affect the prototype chain?
- Adds methods to the subclass only
- Adds methods to the superclass only
- Does not affect the prototype chain
- Adds methods to both the subclass and superclass
In ES6 classes, method definitions impact the prototype chain. When a method is defined in a class, it gets added to the prototype of the class. When a subclass extends a superclass, its prototype chain includes both its own methods and those of the superclass. This ensures proper inheritance and method access.
