wp i18n make-json

Extract JavaScript strings from PO files and add them to individual JSON files.

$ wp i18n make-json <source> [<destination>] [--purge] [--pretty-print]

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.
