Summary Join multiple strings together separated by the specified separator Returns Joined string Remarks Can be passed either an array of strings or a set of strings as arguments Parameters strArray strings to join separator Separator to used to delimit strings, default is an empty string

        "Lorem",
        "ipsum",
        "dolor",
        "sit",
        "amet"
    ]

<strong>result:</strong>

NOTE: The last call in the examples, if you pass in multiple strings instead of a string array, and there are more than two strings passed in, it treats the final string as the separator/delimiator. This means that if you tried {{String.Join "Lorem" "ipsum" "dolor" "sit" "amet"}} and wanted to get back Loremipsumdolorsitamet, then you would actually need to add one more string to your list; ex: {{String.Join "Lorem" "ipsum" "dolor" "sit" "amet" ""}}
