A JavaScript method is a property containing a function definition. Methods are functions stored as object properties. var person = { firstName: "John", lastName : "Doe", id : 5566, fullName : function() { return this.firstName + " " + this.lastName; } }; The this Keyword In a function definition, this refers to the "owner" of the function. In the example above, this is the person object that "owns" the fullName function. In other words, this.firstName means the firstName property of this object. Read more about the this keyword at JS this Keyword. Function A function in JavaScript is similar to a procedure—a set of statements that performs a task or calculates a value, but for a procedure to qualify as a function, it should take some input and return an output where there is some obvious relationship between the input and the output. JavaScript a function allows you to define a block of code, give it a name and then execute it as many times as you want. A function can be defined using function keyword and can be executed using () operator. A function can include one or more parameters. A function is a mapping from a set of inputs (the domain) to a set of possible outputs (the codomain). The definition of a function is based on a set of ordered pairs, where the first element in each pair is from the domain and the second is from the codomain. function myFunction(p1, p2) { return p1 * p2; // The function returns the product of p1 and p2 } myFunction(1*2) Object JavaScript object is a standalone entity that holds multiple values in terms of properties and methods. Object property stores a literal value and method represents function. An object can be created using object literal or object constructor syntax. An object is a collection of properties, and a property is an association between a name (or key) and a value. A property's value can be a function, in which case the property is known as a method. In addition to objects that are predefined in the browser, you can define your own objects. Like all JavaScript variables, both the object name (which could be a normal variable) and property name are case sensitive. You can define a property by assigning it a value. For example, let's create an object named myCar and give it properties named make, model, and year as follows: var myCar = new Object(); myCar.make = 'Ford'; myCar.model = 'Mustang'; myCar.year = 1969; var myCar = { make: 'Ford', model: 'Mustang', year: 1969 };
