That being said, it is fine to use the term “JSON” for these concepts! The reason why it is important to define the term properly before using it is because there is already an established standard for what JSON means.
What most people mean when they say “JSON” is something closer to Javascript-style objects with nested key/value pairs. Technically speaking, this is not quite right. Today, we are going to take a look at some examples of what people refer to as JSON – JavaScript object notation. So how does JSON compare to other ways of defining objects in your software? Well, aside from being much cleaner, it is also slightly faster to process. You could do this very easily using curly brackets, but it would be a lot harder to understand!
For example, say you wanted to define two attributes named ‘first name’ and ‘last name’ that were both set to equal one value – John. It was first described by Doug McIllhenny in 2005 as a more human friendly approach to encoding information.īy defining variables with dashes instead of brackets, it becomes much easier to read which makes it much better than using square braces or parentheses. Technically speaking, it’s called JavaScript object notation (JSON). So what is JSON, you may ask? Well, it’s just an easy way to encode data in a web-based language. Note that there are no quotes around the value these have been inserted for us. This says that the List Item has an ID of 1, and the content inside is ". Next, we will define our first item in the list by inserting another new tag and giving it a nested key/value pair called
This sets up the list style to be like a normal unordered list. First, we will insert a new element named empList, set its value to "EMP LIST", and then for the class attribute we will type `employee'. To begin defining our employees, let's open up your HTML editor and start editing.

We will also add a few methods such as getFullName(), which returns the full name of the employee, and sayHello() which simply prints out the employee’s first name followed by their last name. We will be taking a simple example of an employee structure with two properties – first name and last name. Now it is time to take a closer look at how you would create some basic objects using this method. In our last article, we took a look at why you should use Javascript’s native object literal notation (or “dot notation”) when creating objects. This creates a box with a color of red and a shape of a cube. So our full, well-formed object looks like this: We do the same thing for the bottom face but instead of using 4 lines we use 1 so it becomes a circle. We can make our outer box into an object by adding before the word color and putting a, in between the ] and the next item. The inner box should have four sides and one line segment as its top face. Say you want to make a box, and inside of that box you want to put another box. Now, let’s apply that to some practical examples. That would be equivalent to saying “an object containing a single variable named color and a single variable named shape”. The way it works is pretty simple – you just add square brackets after each property (variable name) and then a comma and the value of that property.įor example, say you wanted to create an object with two properties called color and shape. Many consider this the future of web development because it will eliminate the need to use HTML tags to format your documents and data sets. Today we are going to take a look at something new that has arrived in the programming world, JavaScript object notation or JSON for short.
