Compare JavaScript Object Notation and Initialization File formats — understand the key differences and when to use each

Format Overview

JSON

JavaScript Object Notation

JSON (JavaScript Object Notation) is a lightweight, text-based data interchange format. It uses human-readable key-value pairs and arrays to structure data, making it both easy for developers to work with and efficient for machines to parse. JSON is the dominant format for REST APIs, web services, configuration files, and NoSQL databases (MongoDB, CouchDB). It supports strings, numbers, booleans, arrays, objects, and null values. JSON is language-independent despite its JavaScript origins and is supported by virtually every programming language.
