JSON - What Do We Know About It?

JSON, or Java Script Object Notation, JSON can be defined as a data interchanging format that is lightweight and is easily readable as well. Besides, it is also easy for machines to generate as well as parse JSON. It is based on JavaScript object notation. Therefore, does not need JavaScript to read or write as it comes up in a text format, which is independent of the language.

JSON comes up with the following fundamental elements:

1) Objects: – These start as well as end with braces ({})
2) Object Members: – They consist of values along with strings, which are separated from each other by a colon (:). Members, however, are separated by commas.
3) Arrays: They start as well as end with braces. Each of them contains a certain value, which are separated from each other by commas.
4) Values: Values can be strings, numbers, objects, an array, or literals like true, false, or null.
5) Strings: They are surrounded by double quotes and also come up with Unicode characters as well as common backslash escapes.

So, to put things simply, JSON can be defined as a way in which information can be stored in a streamlined and organized manner so that they can be accessed effortlessly if and when required. In short, Java Script Object Notation facilitates collection of human-readable data that can be accessed in a logical manner.

The salient features of JSON:

Clean Data: The last few years have seen a meteoric rise of Object Oriented Programming in terms of popularity, and a lot of words have already been written describing the benefit of these object oriented programming languages (OOPS). When it comes to using JSON objects, it clearly means that you are able to maintain a strict and standardized structure of the data you are using. The application that receives JSON data knows all the technical nitty-gritty of expectations and way of receiving and utilizing the data. This is very much different from HTML in terms of ways of using. Having an established structure in place will also help the developers in providing various sound and comprehensive cross browser solutions. These solutions are really effective when it comes to various tablets or mobile devices.

Efficiency: In case you are using AJAX for populating any HTML list, you can have an idea about the structure of the HTML structure. While JSON objects are used, it is possible to construct as well as clone the HTML list on the client side. In that case, the only thing that needs to done is changing the information from the server side to the client side. With the development of fast internet connectivity, this optimization makes a huge difference in the usability as well as performance of the web applications.

Scalability: In case the code on the server side is yielding output any standard data format, it becomes much easier to expand or change the application. Re-usability is an extremely important factor, and with all the code on the service code yielding single data structure, it indicates that whatever code is written, it is possible to plug it anywhere it is required.

For example, if the server side code comes up with an HTML list instead of Java Script Object Notation objects. That means, if anyone is looking forward to display the data in an HTML table, it is imperative to re-write the code on the server side as well as on the client side. On the other hand, if the data comes up in the form of structured JSON, all that is needed to be done is changing the way the data will get printed on the screen.

Moreover, JSON is mainly used by a number of languages when there is any need to change the server side language whatever the reason may be. It will be a rather easy transition, mainly because of the standardized structure of JSON, which remains the same across various languages. This would help you leverage the benefits of JavaScript development.

Javascript Tools That Developers Should Be Aware of

A client-side scripting language, JavaScript is a powerful tool when it comes to developing websites or web applications. When used by a skilled developer, it can work impressively to enhance the user experience. It also provides rich features and components. Syntactically JavaScript is an easy language to master but it is often predicted as a difficult language to work with owing to its environment – the Web browser. The popularity of JavaScript can be estimated from the way the latest technologies utilize it as a supported language for developing desktop apps. There are several tools within this language that help in speeding up the coding process, optimize codes and test the scripts in various situations. Besides these, they are also applied for unit testing, check security vulnerabilities and as debugging tools.

Here’s a list of JavaScript tools that the developers should be aware of:

JS Nice: This helps in reading the JavaScript codes even if it is obfuscated. In this sort of a program the JS Nice suggests new identifier types as well as names automatically. By using advanced techniques for program analysis as well as machine learning it can learn the name and type regularities from vast amount of open source projects.

Converse. Js: It is an open source chat app that can be used to connect to any Jabber or XMPP server. You will also find it in the footer of the webpages, such as, Facebook chat and acts as a support to one to one or multi-user conversations. This tool is used to decline or accept contact requests, set statuses, etc.

Hitch: This provides an extension model for both HTML as well as CSS. Hitch is defined as a prollyfill engine for JavaScript. By using this tool the developers easily import and utilize features from CSS selectors that have been merely proposed or HTML widgetry that is based on the previous web components proposal.

Responsive Nav: This is another JavaScript plugin that makes the creation of responsive menus a simple task for the developers. CSS3 transitions and touch events are used by this tool to ensure impressive performance. This also works well on screen readers even when the JavaScript is disabled. There are standalones in this plugin too. The developers can also make use of the callbacks for init, close and open events.

amMap: To include an interactive map functionality to the webpages the developers make use of the amMap. It is sued to display the locations of an office or the route through which one daily travels, etc. A distributor map can also be created by applying this tool. In addition to these, the developers can also include images or illustrations as backgrounds or layers in the maps. This would make a huge difference in the presentation or the e-learning tools.

Sequel.Js: For building the SQL query Squel.js is used as it strings conveniently through an object related to the API. It supports all kinds of SQL queries. It can work also on the browser. But the latter is not advisable as the queries in this case will be visible to all.

Candy: Another open source chat app that has been created with the help of this language. It uses Jabber in developing real time based communication. The added advantage for this open source tool is that it receives support from various rooms. Therefore the users can be active in multiple numbers of rooms. They can also chat both privately as well as publicly. These can be performed in impressive tabbed interfaces.

Radi: It is a visual design app that targets the web with both standard as well as human readable HTML, JavaScript code. There are built in tools for editing and creating graphics. The animations can be generated in the canvas output that works fine in all the modern browsers and even in handheld devices as well. For a more customized effect the filters (ready to use) as well as effects can be used by adding them in the developer’s codes.

Roole: If you are looking for an alternative that is SASS or LESS (+stylus) inspired then check out Roole. It supports variables as well as conditional logic. The reason why developers should use it is because it enables to define the format used in the CSS. It is a well documented tool that works on both the server side and client side.

As a developer if you are planning to use JavaScript as a programming language, these are some of the tools that you must be aware of. This would help you leverage the benefits of JavaScript development.
