### Grouped Loop Simple Example

Source: https://neos.readthedocs.io/en/9.1/References/ViewHelpers/TYPO3Fluid.html

Demonstrates a simple grouped loop using the f:groupedFor ViewHelper. It iterates over a list of fruits and groups them by color.

```fluid
<f:groupedFor each="{0: {name: 'apple', color: 'green'}, 1: {name: 'cherry', color: 'red'}, 2: {name: 'banana', color: 'yellow'}, 3: {name: 'strawberry', color: 'red'}}"

### Commit Message Structure Example

Source: https://neos.readthedocs.io/en/9.1/Contribute/Documentation/BeginnersGuide.html

Illustrates the standard format for commit messages, including type, summary, detailed explanation, and issue tracking footers.

```text
TASK: Short (50 chars or less) summary of changes

More detailed explanatory text, if necessary. Wrap it to about 72 characters or so. In some contexts, the first line is treated as the subject of an email and the rest of the text as the body. The blank line separating the summary from the body is critical (unless you omit the body entirely); tools like rebase can get confused if you run the two together.

Write your commit message in the present tense: “Fix bug” and not “Fixed bug.” This convention matches up with commit messages generated by commands like git merge and git revert.

Further paragraphs come after blank lines.
  * Bullet points are okay, too
  * An asterisk is used for the bullet, it can be preceded by a single space. This format is rendered correctly by Forge (redmine)
  * Use a hanging indent

A first step in solving neos/flow-development-collection#789.
Fixes #123
Closes #456
```

--------------------------------

### Array.every Example

```

--------------------------------

### Create Link to Action (Defaults)

Source: https://neos.readthedocs.io/en/9.1/References/ViewHelpers/FluidAdaptor.html

Generates a link to the current package, controller, and action. The exact output depends on the routing setup.
