ES6 - String Prototype


Advertisements


The prototype property allows you to add properties and methods to any object (Number, Boolean, String, Date, etc.).

Note − Prototype is a global property which is available with almost all the objects.

Syntax

string.prototype

Example : Object prototype

function employee(id, name) { 
   this.id = id; 
   this.name = name; 
} 
var emp = new employee(123, "Smith"); 
employee.prototype.email = "smith@abc.com"; 

console.log("Employee 's Id: " + emp.id); 
console.log("Employee's name: " + emp.name);
console.log("Employee's Email ID: " + emp.email);

Output

Employee’s Id: 123 
Employee’s name: Smith 
Employee’s Email ID: smith@abc.com
