What is the prototype chain in JavaScript?
The prototype chain is a mechanism in JavaScript that allows objects to inherit properties and methods from other objects.
How does inheritance work with the prototype chain?
Inheritance works by linking objects through their prototypes, allowing a child object to access properties of its parent.
Can you give me an example of the prototype chain in action?
Sure! If you have an object dog
that inherits from animal
, calling dog.bark()
will look up the prototype chain to find bark
in animal
.
What happens if a property is not found in the object?
If a property is not found in the object, JavaScript will continue to search up the prototype chain until it finds the property or reaches the end.
