## Description

js-beautify is a web language beautifier and rule-based code stylizer designed to standardize the indentation and layout of JavaScript, HTML, and CSS. It converts minified or obfuscated source code into a human-readable format to improve maintainability and readability.

The system enforces consistent coding styles through global configuration files and programmatic options. It also supports local formatting overrides, allowing users to control behavior for specific sections of a file using embedded comment directives.

The project provides capabilities for source code style enforcement and web language standardization. This includes the ability to apply specific brace styles, indentation rules, and line wrap lengths across different web-based languages.
