JSON Knowledge
What is JSON?
Basic JSON Structure
JSON consists of two basic structures: key-value pair collections (objects) and ordered value lists (arrays). Objects are key-value pair collections enclosed in curly braces, arrays are value lists enclosed in square brackets.
JSON Application Scenarios
JSON is commonly used for data transmission between web applications, API response formats, configuration files, data storage formats for NoSQL databases (such as MongoDB), and other scenarios.
Importance of Formatting
Formatted JSON is more readable, facilitates debugging and understanding complex data structures for developers, and helps maintain consistency in code style during team collaboration.
Common JSON Errors
Common JSON errors include: missing commas, strings not enclosed in double quotes, key names not enclosed in double quotes, extra commas, using JavaScript comments, etc.
JSON vs. Other Formats
Compared to XML, JSON is more lightweight and has faster read/write speeds; compared to CSV, JSON supports complex data structures. However, for simple tabular data, CSV may be more efficient.
