![]() ![]() Objects are sometimes called associative arrays, since each property is associated with a string value that can be used to access it. Properties of JavaScript objects can also be accessed or set using a bracket notation. For example, let’s create an object named m圜ar and give it properties named make, model, and year as follows: var m圜ar = new Object() You define a property by assigning it a value. Like all JavaScript variables, both the object name (which could be a normal variable) and property name are case sensitive. You access the properties of an object with a simple dot-notation: objectName.propertyName The properties of an object define the characteristics of the object. Object properties are basically the same with ordinary JavaScript variables, except for the attachment to objects. A property of an object can be explained as variables that are attached to the object. Objects and propertiesĪ JavaScript object has properties associated with it. The same way, JavaScript objects can have properties, which define their characteristics. ![]() A cup has a colour, a design, weight, a material it is made of, etc. In JavaScript, an object is a standalone entity, with properties and type. The concept of objects in JavaScript can be understood with real life, tangible objects. Objects in JavaScript, just as many other programming languages, can be compared to objects in real life. This chapter describes how to use objects, properties, functions, and methods, and how to create your own objects. In addition to objects that are predefined in the browser, you can define your own objects. A value of property can be a function, which is then known as the object’s method. JavaScript is designed on a simple object-based paradigm: An object represents a collection of properties each property is an association between a name/value pair. Objects are integral to javascript development and understanding how objects are generated and used is essential. Working with objects in JavaScript Summary
