## What it is
Jsawk is a command-line tool that works like awk but for JSON, filtering and transforming arrays of JSON objects read from stdin using JavaScript snippets. It is a shell script that relies on the SpiderMonkey js interpreter and can pipe results to other processes or load JavaScript libraries.

## Use cases
- filter JSON arrays from a REST API in a shell script
- transform JSON data into other text formats on the command line
- modify fields of JSON objects fetched via curl or resty before PUT requests
- query and extract values from JSON in bash pipelines
- preprocess or postprocess JSON arrays with custom JavaScript snippets

## When to choose
- you need awk-style JSON filtering in shell scripts
- you want a lightweight single-script tool with no heavy dependencies beyond a js interpreter
- you pipe JSON between REST endpoints and other command-line tools

## When to avoid
- you need actively maintained software with recent updates or a license
- you prefer modern tools like jq with richer query syntax
- you work in environments where installing SpiderMonkey is impractical
