The “Number” data type is a signed decimal number it makes no distinction between integers (whole numbers) or floating point (numbers with decimal points). JSON has several data types that can be used in its structure. It is a serial-based protocol that presents the data in a simple readable form. While there are smaller and faster ways to transmit and share data, JSON grew from the need to have a real-time, user-readable communication protocol for use in modern browsers, without the use of plugins. Although the J on the acronym stands for JavaScript, you are by no means forced into using this language, as it is language-independent because of this, we can use it with nearly all modern languages. It is one of the most commonly used asynchronous data types, and is seen as a replacement to XML in some systems. It consists of data objects that are attribute-value pairs, and array-style data types. JSON stands for “JavaScript Object Notation”, and it is a text-based, open-standard file notation that transmits text in a human-readable form. ![]() JSON offers us a solution that will help you, and anyone else who joins the project, to develop a scalable and rich data processes. This can prove to be inherently complex as the project grows. We can program the receiver to accept 1 piece of data at a time or we may add to this and start sending 2 numbers, or 15! Being that we are working with both sending and receiving the data, we are essentially developing our own data protocol. ![]() It is quite simple for us to send a single number – one at a time – to the receiver. For example, we may build a wireless controller to send commands to a robot that we are working on. We need to establish a way to get our data from one point to another. This comes with one inherent issue: how do we conform our data to be readable by another system or programmer at a later date? THE BROAD OVERVIEW Transfer of data and data protocols We start to store our data on servers in databases, or SD cards attached to our microcontrollers. As our programming needs grow, so too does the complexity of the data. As the equations get more complex, the basic principle remains the same: take the inputs, perform equations, output results. It serves a single purpose, takes one or two discrete or computed numbers, performs a mathematical function and then outputs them to the user. Take for example, the humble calculator app on your phone or system. So how can we get the information we need, to the place we need it to be?Īt its core, programming is the input of a piece of data and then the output of that data, be it for computation or storage. Internally it can be quite simple, but there may be times when we do not know how the receiving system will require its data. Forever playing by the rules, JSON is a powerful, yet talented container for information.Īt the most basic level, programming is about the transfer of data from one point to another.
