In Javascript design pattern term is used for a reusable solution for commonly occurring problems in Javascript. The constructor design pattern is a class-based design pattern. Constructors are special functions that can be used to instantiate new objects with methods and properties defined by that function. Constructor pattern is one of the most commonly used patterns in JavaScript<\/a> for creating new objects of a given kind.<\/p>\n

Example of Constructor Design Pattern
\nInput:<\/strong>
\n\/\/ using constructor function
\nlet User = function(firstName, lastName, emailId, age){
\nthis.firstName = firstName;
\nthis.lastName = lastName;
\nthis.emailId = emailId;
\nthis.age = age;
\nthis.getFullName = function (){
\nreturn this.firstName + \" \" + this.lastName;
\n}
\n}
\nvar user1 = new User('Ramesh', 'Fadatare', 'ramesh24@gmail.com', 29);
\nvar user2 = new User('John', 'Cena', 'john@gmail.com', 45);
\n\/\/ Print objects
\nconsole.log(user1);
\nconsole.log(user2);
\n\/\/ access properties
\nconsole.log(user1.firstName);
\nconsole.log(user1.lastName);
\nconsole.log(user1.age);
\n\/\/ calling method
\nconsole.log(user1.getFullName());<\/code><\/p>\n

Output:<\/strong>
\nUser {firstName: \"Ramesh\", lastName: \"Fadatare\", emailId: \"ramesh24@gmail.com\", age: 29, getFullName: \u0192}
\nUser {firstName: \"John\", lastName: \"Cena\", emailId: \"john@gmail.com\", age: 45, getFullName: \u0192}
\nRamesh
\nFadatare
\n29
\nRamesh Fadatare<\/code><\/p>\n
