A lightweight, dependency-free JavaScript library for converting XML to JSON and JSON to XML.
x2js is a JavaScript library that converts XML data to JSON and vice versa. It solves the problem of working with XML in JavaScript applications by transforming XML documents into easily manipulable JavaScript objects and enabling serialization of JSON back to XML format.
JavaScript developers who need to parse XML responses from APIs, work with legacy XML-based systems, or handle XML data interchange in web or Node.js applications.
Developers choose x2js for its zero dependencies, small size, and highly configurable conversion options, providing fine-grained control over XML/JSON transformation without the bloat of larger libraries.

The library has no external dependencies, keeping it lightweight and easy to integrate without bloating bundle sizes, as stated in the README.
Offers extensive configuration options for handling attributes, arrays, namespaces, and date-times, allowing fine-tuned control over XML/JSON transformation based on the documented settings.
Provides both XML to JSON and JSON to XML conversions with methods like xml_str2json and json2xml_str, enabling seamless data interchange in web applications.
Includes utility functions such as asArray for consistent array access and asDateTime for XML date-time conversion, simplifying common tasks as shown in the examples.
The numerous config options, like arrayAccessFormPaths and datetimeAccessFormPaths, require upfront knowledge of XML structure, adding setup complexity for dynamic or unknown schemas.
Relies on older JavaScript patterns such as constructor-based instantiation and lacks support for modern features like Promises for asynchronous operations, as seen in the AJAX samples using XMLHttpRequest.
Uses prefixes like '_' for attributes and special properties like '__text', which can clutter the resulting JSON objects and necessitate additional processing to clean up.
