Function chaining in javascript

Function chaining is also called cascading.

Method chaining is a technique that can be used to simplify code in scenarios that involve calling multiple functions on the same object consecutively.

User Details example without function chaining

 	var User = function (){ 		this.name = 'xyz'; 		this.age = 30; 		this.gender = 'male'; 	};  	User.prototype.setName = function(name) { 	  	this.name = name; 	};  	User.prototype.setAge = function(age) { 	  	this.age = age; 	};  	User.prototype.setGender = function(gender) { 	  	this.gender = gender; 	};  	User.prototype.print = function() { 	  console.log('My Name is '+ this.name + '. I am a '+ this.gender +'. My age is ' +this.age); 	}  	var obj = new User(); 	 	obj.setName('Anil Kapoor'); 	obj.setAge(27); 	obj.setGender('male');  	obj.print(); 

Implementing Function Chaining

 	var User = function (){ 		this.name = 'xyz'; 		this.age = 30; 		this.gender = 'male'; 	};  	User.prototype.setName = function(name) { 	  	this.name = name; 	  	return this; 	};  	User.prototype.setAge = function(age) { 	  	this.age = age; 	  	return this; 	};  	User.prototype.setGender = function(gender) { 	  	this.gender = gender; 	  	return this; 	};  	User.prototype.print = function() { 	  console.log('My Name is '+ this.name + '. I am a '+ this.gender +'. My age is ' +this.age); 	}  	var obj = new User(); 	 	obj.setName('Anil Kapoor').setAge(27).setGender('male').print();
