Can JavaScript parent and child classes have a method with the same name?

Yes, parent and child classes can have a method with the same name.

Example

class Parent {    constructor(parentValue) {       this.parentValue = parentValue;    }    //Parent class method name which is same as Child Class method name.    showValues() {       console.log("The parent method is called.....");       console.log("the value is="+this.parentValue);    } } class Child extends Parent {    constructor(parentValue,childValue){       super(parentValue);       this.childValue = childValue;    }    //Child class method name which is same as Parent Class method name.    showValues() {       console.log("The child method is called.....");       console.log("The value is="+`${this.childValue}`);    } } var parentObject = new Parent(100); parentObject.showValues(); var childObject = new Child(400,500); childObject.showValues();

To run the above program, you need to use the following command −

node fileName.js.

Here, my file name is demo195.js.

Output

This will produce the following output −

PS C:\Users\Amit\javascript-code> node demo195.js The parent method is called..... the value is=100 The child method is called..... The value is=500
