Comment ViewHelper <f:comment>
Note
This reference is part of the documentation of Fluid Standalone. If you are working with Fluid in TYPO3 CMS, please refer to TYPO3's ViewHelper reference instead.
This ViewHelper prevents rendering of any content inside the tag.
Contents of the comment will not be parsed thus it can be used to comment out invalid Fluid syntax or non-existent ViewHelpers during development.
Using this ViewHelper won't have a notable effect on performance, especially once the template is parsed. However, it can lead to reduced readability. You can use layouts and partials to split a large template into smaller parts. Using self-descriptive names for the partials can make comments redundant.
