Objectifying JavaScript

While it is not a good idea to objectify people, objectifying JavaScript is a good idea. When I build apps, I use objects in every one of them. Objects are great because they are not only easy to work with, but they also emulate their real world counterparts.

In this post, I want to show simply how to create objects in JavaScript as there are several ways to accomplish this.

First Way to Create Object

You can just use curly braces to create the object…

var firstObj = {};

Second Way to Create Object

The next way is to use object.create. It takes whatever you pass in and wrap it in an object. It then hands you back the object…

var secondObj = Object.create(Object.prototype);

This is used when you wish to do inheritance. You create an object and pass it in and the object inherits items from the parent object.

Third Way to Create an Object

The third manner to create an object is to use the new object. Historically, in the JS world, this has gotten some bad press. If you come from a classic object-oriented language, it will look familiar. I would encourage those that have believed the “bad press” to reconsider. Beginning with ES6 (ECMAScript 6), JS has the class operator, which allows the ability to build classes in JS. The new object allows JS to follow the same conventions as classical OOP languages…

var thirdObj = new Object();

So, those are the three ways. You can use any of them. Some are used due to personal preference, while others are by convention. I would encourage you to try all three.

Happy Coding!

Unlocking Wireless Communication: A Dive into the Bluetooth API

Wireless communication has become an integral part of our daily lives, and Bluetooth technology is at the forefront of this revolution, enabling devices to exchange data over short distances and creating a world more interconnected than ever before. At the heart of this technology lies the Bluetooth Application Programming Interface (API), a powerful tool for developers looking to harness the capabilities of Bluetooth in their applications. In this blog post, we’ll explore what the Bluetooth API is, how it works, and the possibilities it opens up for innovation in wireless communication.

Understanding the Beacon API: Simplifying Asynchronous Data Transfers

In today’s data-driven world, web applications often need to send data back to the server. Traditionally, this has been done using AJAX requests or similar methods. However, these techniques can come with a cost, especially when dealing with data that needs to be sent during the unload phase of a document, such as tracking and diagnostic data. This is where the Beacon API shines by allowing developers to send data to a server more reliably and efficiently.
