With increasing reliance on technology and the need for data exchange between systems, it’s important to have a clear understanding of JSON and its applications

What is JSON (JavaScript Object Notation)?JSON (JavaScript Object Notation) is a text-based format for storing and exchanging data in a way that’s both human-readable and machine-parsable. As a result, JSON is relatively easy to learn and to troubleshoot. Although JSON has its roots in JavaScript, it has grown into a very capable data format that simplifies data interchange across diverse platforms and programming languages. If you're involved in web development, data analysis, or software engineering, JSON is an important data format to understand.Why is JSON used?JSON's language-independent nature makes it an ideal format for exchanging data across different programming languages and platforms. For instance, an application written in Java can easily send JSON data to a Python application. Or a mobile app written in JavaScript can use JSON to communicate with a back-end server written in PHP. Why? Because both systems can parse and generate JSON. Beyond web development, JSON is often used within an application or an IT system for storing and managing configuration settings. For example, configuration files written in JSON format can contain essential information, such as database connection details, API keys, or user preferences. By storing configuration data in simple, easy-to-read and easy-to-parse JSON files, developers can modify application settings without requiring code changes.Why is JSON popular with developers?JSON is popular with developers because it’s a flexible format for data exchange that enjoys wide support in modern programming languages and software systems. It’s text based and lightweight and has an easy-to-parse data format, meaning it requires no additional code to understand and interpret the data provided. JSON has gained momentum in API programming and web services because it delivers faster data interchange and web service results. It also helps that developers have ready access to open source, NoSQL document databases, such as MongoDB and others, that store data in JSON format and require no additional processing when they exchange data. Popular relational databases can now handle JSON as a native format, opening even more applications to the benefits of JSON.
JSON je textový, na jazyce zcela nezávislý formát, využívající však konvence dobře známé programátorům jazyků rodiny C (C, C++, C#, Java, JavaScript, Perl, Python a dalších).
