Version

• .NET 4.13.1
• JavaScript 4.13.1

Describe the bug

Using the prebuilt function join() and passing in an array of arrays, we get different results.

Assuming an array of arrays, such as: {"Foods":[["Burger"],["Pizza"]]}, the expression join(Foods, ',') will give a result of the following, depending on SDK/Language:

Javascript: Burger,Pizza
.NET: [ "Burger" ],[ "Pizza" ]

Expected behavior

Should be consistent regardless of runtime language.
