Methods [/su_headings] 

Methods are functions that are stored as object properties.

Use the following syntax to create an object method:

methodName = function() { code lines

 

Access an object method using the following syntax:

objectName.methodName() 

 

A method is a function, belonging to an object. It can be referenced using the this keyword.
The this keyword is used as a reference to the current object, meaning that you can access the objects properties and methods using it.

Defining methods is done inside the constructor function.

For Example:

function person(name, age) {
  this.name = name; 
  this.age = age;
  this.changeName = function (name) {
    this.name = name;
  }
}

var p = new person(“David”, 21);
p.changeName(“John”);
//Now p.name equals to “John” 

 

In the example above, we have defined a method named changeName for our person, which is a function, that takes a parameter name and assigns it to the name property of the object.
this.name refers to the name property of the object.

NOTE!
The changeName method changes the object’s name property to its argument.
