Introduction

JSON (JavaScript Object Notation) is a lightweight data exchange format based on a subset of the JavaScript language and widely used for data transmission and storage. JSON uses key-value pairs to represent data, uses a simple, easy-to-read text format, and is also easy to parse and generate, making it a common data exchange format.

Applicable Scene

JSON is the most common application scenario for data exchange between front-end and back-end. It is a commonly used data format in Web APIs because of the convenience of parsing JSON in JavaScript, and it is also easy to process in other programming languages. Because of JSON’s readability, it is also commonly used for logging and tracking the running status of applications.

Pros: JSON uses a simple key-value pair structure, which is easy to read and edit, and it is also convenient for manual writing and generation. JSON is a common data format, and almost all programming languages support JSON parsing and generation, so it is suitable for data exchange between different platforms and systems.

Cons: Values in JSON have no type information, so when parsing JSON data, it is necessary to determine the type of the value according to convention or other means in order to use the data correctly. JSON does not support comments, so it is not possible to add comments to JSON data, which can make the document verbose in some cases.
