Can you explain what constructor inheritance is in JavaScript?
Sure! Constructor inheritance allows one constructor function to inherit properties and methods from another constructor function.
How do you implement constructor inheritance?
You can implement it using the call
or apply
methods, or by setting the prototype of the child constructor to an instance of the parent.
Can you give me a code example?
Absolutely! Here's a simple example:
function Parent() {
this.parentProperty = 'I am a parent';
}
function Child() {
Parent.call(this); // Inherit properties
this.childProperty = 'I am a child';
}
Child.prototype = Object.create(Parent.prototype); // Inherit methods
Child.prototype.constructor = Child;
What are the advantages of using constructor inheritance?
Constructor inheritance promotes code reuse and helps in organizing code better by allowing child objects to inherit from parent objects.
