What Are the Object Property Accessors in JavaScript?

You can access object properties in JavaScript in one of two ways: . dot syntax or [] bracket notation. Here’s why there are two property accessors and what the difference is between them.

One of the first things JavaScript developers learn is that there is a difference between primitive types (like numbers and booleans) and objects (like arrays and Dates).

You typically recognize objects because they are invoked with the object literal syntax ({}, curly brackets) and then accessed using a single period character, the . dot syntax.

Calling the . dot syntax is what is called an object property accessor, as it allows you to access the specified property.

One of the nice things about learning JavaScript these days is that there is a plethora of choices for writing and running JavaScript code. In this article, I’m going to describe a few of these environments and show you the environment I’ll be using in this series of articles.

To paraphrase the title of an old computer science textbook, “Algorithms + Data = Programs.” The first step in learning a programming language such as JavaScript is to learn what types of data the language can work with. The second step is to learn how to store that data in variables. In this article I’ll discuss the different types of data you can work with in a JavaScript program and how to create and use variables to store and manipulate that data.

Microsoft has released a new series of video tutorials on YouTube for novice programmers to get a hands-on renowned programming language — JavaScript.

In this post, I will explain why declarative code is better than imperative code. Then I will list some techniques to convert imperative JavaScript to a declarative one in common situations.
