An expression to check if an array contains a string

[jc211]

I have a geojson property which is an array. I would like to have an expression that checks if that array contains a certain string.
['has', 'mystring', ['get', 'myarray']]

Is this possible currently? If not, would it be possible to make the existing 'has' expression operate on arrays as well as objects?

It's not possible currently, but I agree that it's something we should add.

I recently discovered that I am in need of a similar expression, but that also takes an array input containing multiple strings and compares them to the values in the feature array property, is that possible to look at in the same issue?

That's too bad, is there a workaround?
What if I'm able to explode the array as a comma separated string or something?
Could I use an expression to search for the presence of the value as part of another string?
Thanks!

@Twansparant that also doesn't yet exist, but is something we're planning to add. Most directly tracked at #6228
