This object gives you the ability to instantiate an object without giving it any data. This is the base object to create custom objects within your code. Notice that this code instantiates the internal 'Object()' object. The following code also creates a customer object, but the data isn't filled until after the object is created. JavaScript lets you create standard objects without defining any custom data on-the-fly. What if you don't have data that you want to use for an object? No problem. In this example, we've created a custom object named 'customer.' We've then created properties named 'first_name,' 'last_name,' and 'phone.' After the colon, we've defined values for these properties. This keyword tells JavaScript that we're creating a variable. But, let's start with creating a customer object with some standard properties.

The amount of properties for a customer is up to you and how you design your application. A customer has an address, phone number, first name and last name. You have customers, orders, products, and information related to these objects. For instance, if you have an ecommerce site, you have different parts of your site related to the store. An object defines a set of properties related to a specific part of your application. This article discusses how to create and work with objects including arrays.īefore you can write an object variable, you should understand the premise of an object. The objects are given a name, and then you define the object's properties and property values. An array is an object also, except arrays work with a specific number of values that you can iterate through. JavaScript lets you create objects and arrays.

JavaScript is more than just strings and numbers.
