# Breaking: #83161 - Remove TYPO3.LLL usages in TYPO3 core {#breaking-83161}

See [forge#83161](https://forge.typo3.org/issues/83161)

## Description {#description}

After moving to the `TYPO3.lang` API for javascript, the `TYPO3.LLL` is not needed anymore.

## Impact {#impact}

All extensions which are using `TYPO3.LLL` for translation in javascript should be checked and updated accordingly.

## Affected Installations {#affected-installations}

Any installation using extensions, which are using `TYPO3.LLL`.

## Migration {#migration}

Use `TYPO3.lang['label']` from javascript. To make custom language labels available in javascript,
add `$this->pageRenderer->addInlineLanguageLabelFile('EXT:foo/Resources/Private/Language/locallang.xlf');`
in your backend controller.

The class typo3/sysext/feedit/Classes/FrontendEditAssetLoader.php was removed, so if you used it in your code you have to remove the dependency.
