/**
* Extract JavaScript strings from PO files and add them to individual JSON files.
*
* For JavaScript internationalization purposes, WordPress requires translations to be split up into
* one Jed-formatted JSON file per JavaScript source file.
*
* See https://make.wordpress.org/core/2018/11/09/new-javascript-i18n-support-in-wordpress/ to learn more
* about WordPress JavaScript internationalization.
*
* ## OPTIONS
*
* <source>
* : Path to an existing PO file or a directory containing multiple PO files.
*
* [<destination>]
* : Path to the destination directory for the resulting JSON files. Defaults to the source directory.
*
* [--purge]
* : Whether to purge the strings that were extracted from the original source file. Defaults to true, use `--no-purge` to skip the removal.
*
* [--update-mo-files]
* : Whether MO files should be updated as well after updating PO files.
* Only has an effect when used in combination with `--purge`.
*
* [--pretty-print]
* : Pretty-print resulting JSON files.
*
* [--use-map=<paths_or_maps>]
* : Whether to use a mapping file for the strings, as a JSON value, array to specify multiple.
* Each element can either be a string (file path) or object (map).
*
* ## EXAMPLES
*
* # Create JSON files for all PO files in the languages directory
* $ wp i18n make-json languages
*
* # Create JSON files for my-plugin-de_DE.po and leave the PO file untouched.
* $ wp i18n make-json my-plugin-de_DE.po /tmp --no-purge
*
* # Create JSON files with mapping
* $ wp i18n make-json languages --use-map=build/map.json
*
* # Create JSON files with multiple mappings
* $ wp i18n make-json languages '--use-map=["build/map.json","build/map2.json"]'
*
* # Create JSON files with object mapping
* $ wp i18n make-json languages '--use-map={"source/index.js":"build/index.js"}'
*
* @when before_wp_load
*
* @throws WP_CLI\ExitException
