How to Access the Name Field of the First Element in a Go Template Array?

Accessing the First Array Element's Value in Go Templates

When working with Go templates and arrays, accessing the value of the first index can be challenging. In this scenario, you're trying to retrieve the Name field of the first element in the Doc.Users array.

The solution lies in properly grouping the expression and applying the .Name selector:

<div>Foobar {{ (index .Doc.Users 0).Name }}</div>

Here's how this works:

1. index .Doc.Users 0 retrieves the first element of the Doc.Users array, providing a nested object.
2. ( ) groups this nested object, allowing you to apply selectors on it.
3. .Name then selects the Name field from the grouped object.

This approach ensures you access the Name field of the first Doc.Users element as required.
