This extension is intended for frontend developers.
It generates language labels in JavaScript from a list of extension locallang files (e.g. locallang.xml),
saves the resulting JavaScript locallang array in the typo3temp directory and inserts a link to the saved filed into the page header.
The resulting language labels can be applied dynamically in frontend JavaScript applications.
Its a modernized approach to the outdated extension rtp_locallang_js
