​​​​​​​​​​​Json script JSON SCRIPTJSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate. It is based on a subset of the JavaScript programming language, Standard ECMA-262 3rd Edition - December 1999. JSON is often used to transmit data between a server and web application as an alternative to XML.With JSON, you can easily represent complex data structures in a readable and concise manner. It consists of key-value pairs, similar to objects in JavaScript. Here is an example of a simple JSON object:{ "name": "John Doe", "age": 30, "city": "New York" }In this object, "name", "age", and "city" are keys, while "John Doe", 30, and "New York" are the corresponding values. Arrays can also be represented in JSON using square brackets. Here is an example:{ "employees": ["Alice", "Bob", "Charlie"] }JSON is commonly used in web development for sending and receiving data from APIs. It is language-independent, meaning it can be used with any programming language that has a JSON parser. Parsing JSON is straightforward in most programming languages. For example, in JavaScript, you can parse a JSON string into an object using the JSON.parse() method. Here is an example:javascript const jsonStr = '{"name": "Jane Doe", "age": 25}'; const obj = JSON.parse(jsonStr);console.log(obj.name); // Output: Jane Doe console.log(obj.age); // Output: 25 Likewise, you can convert a JavaScript object into a JSON string using the JSON.stringify() method. Here is an example:javascript const obj = { name: "Alice", age: 35 }; const jsonStr = JSON.stringify(obj);console.log(jsonStr); // Output: {"name":"Alice","age":35} In conclusion, JSON is a versatile and widely-used data format that simplifies data interchange in web applications. Its simplicity and ease of use make it a popular choice for developers when working with data.
JSON против XML: сравнение двух форматов данных
Читать на оригинальном сайте статью с хорошим форматированием кода Введение Определение JSON и XML JSON и XML — это форматы обмена данными, используемые для передачи данных между сервером и веб-приложением или между различными системами. JSON (JavaScript Object Notation) — это текстовый формат, который используется для хранения и обмена данными в виде объектов JavaScript. Это упрощенный формат данных, в котором для передачи объектов данных, состоящих из пар ключ-значение, используется удобочитаемый текст...
