Passing array of strings to native JavaScript plugin on WebGL

I’m working on integrating an API on a WebGL project, and I need to pass an array of strings to a native plugin. Here’s a snippet of my native plugin code in JavaScript:

WebGetValues: function(textIds)
    opt_params = {};
    var ids = {};
    for (var i = 0; i < textIds.length; i++)

I’m not seeing a console log, which leads me to believe that it’s either not being passed in as an array or the data is invalid. Here’s how I’m passing in the string array from C#:
public void GetValues(IEnumerable textIds)

I couldn’t find anything in the documentation or anywhere online about passing in string arrays to native JS plugins. Is there a way to do this?

I came up with a solution that involved passing in a string delimited by a less common character (Ex. ‘;’ or ‘|’) since I’m dealing with JSON data. On the JS side, I split the string using that delimiter, which gives me all the info I need in an array.
