A common use of JSON is to read data from a web server, and display the data in a web page. For simplicity, this can be demonstrated using a string as input. First, create a JavaScript string containing JSON syntax: vartext ='{ "employees" : ['+ ...
The two primary parts that make up JSON are keys and values. Together they make a key/value pair.Key: A key is always a string enclosed in quotation marks. Value: A value can be a string, number, boolean expression, array, or object. Key/Value Pair: A key value pair follows a ...
Key Differences JSON(JavaScript Object Notation) is commonly used for data storage and transfer. JSON is a popular choice for applications that benefit from a simple and easy-to-use data format. XML(Extensible Markup Language) is a general-purpose markup language similar to JSON that allows for...
JSON is quick to learn for the user and can be integrated quickly into existing systems.The simple implementation and the short training period are the main advantages of JSON.Additionally, JSON is already readable by many common programming languages.There is a so-called Parser, which translates...

Data is presented inkey/valuepairs. Data elements are separated by commas. Curly brackets{}determine objects. Square brackets[]designate arrays. As a result, JSON object literal syntax looks like this: {“key”:“value”,“key”:“value”,“key”:“value”.} ...
Arrays in JSON are surrounded by square brackets, like these [ ]. Each value in the array is separated by a comma. Users can access array values and update, delete or loop them. An array can be stored inside another JSON array; that's called amultidimensional array. ...
JSON represents data in two ways: Object: a collection of name-value (or key-value) pairs. An object is defined within left ({) and right (}) braces. Each name-value pair begins with the name, followed by a colon, followed by the value. Name-value pairs are comma separated. ...
