JSONrakenteet

JSONrakenteet refers to the fundamental building blocks used to construct JSON (JavaScript Object Notation) documents. These structures define how data is organized and represented in a universally readable format. The two primary JSON structures are objects and arrays.

A JSON object is an unordered collection of key-value pairs. The keys are always strings, enclosed in double quotes, and the values can be any valid JSON data type. Keys and values are separated by a colon (:), and the pairs are separated by commas (,). The entire object is enclosed in curly braces {}. For example, {"nimi": "Matti", "ika": 30} represents an object with two key-value pairs.

A JSON array is an ordered list of values. Values within an array are separated by commas (,) and the entire array is enclosed in square brackets []. The values in an array can be of different data types. For instance, [1, "omena", true, null] is a valid JSON array.

These basic structures, objects and arrays, can be nested within each other to create complex and hierarchical data representations. For example, an object can contain an array as a value, or an array can contain objects. This nesting capability makes JSON highly flexible for representing diverse data structures, from simple configuration settings to intricate database records.
