Interactive JSON Viewer
fx provides an interactive command-line JSON viewer that allows users to explore and manipulate JSON data intuitively.
Simple and Lightweight
The tool is compact and easy to use, making it an excellent choice for users who need quick data examination without complex setup.
Scriptable
Users can use JavaScript expressions to filter and transform JSON data, offering flexibility in data manipulation.
Integration
fx can be easily integrated into shell scripts and other command-line tools due to its standard input/output operations.
Cross-Platform Compatibility
Being a Node.js-based tool, fx is cross-platform and can run on multiple operating systems supporting Node.js.

Possible disadvantages

Limited Functionality
fx is designed primarily for viewing and transforming JSON, so it may not have advanced features found in full-fledged data processing tools.
JavaScript Requirement
Users need to be familiar with JavaScript to effectively use fx's data transformation features, which might be a barrier for non-programmers.
Command-Line Only
As a command-line tool, fx lacks a graphical user interface, which might be less appealing for users who prefer visual data interaction.
Performance
Handling very large JSON files may lead to performance issues, as fx is primarily built for lightweight quick tasks.
