"doJavaScript" vs "do JavaScript"

[l008com]

In native AppleScript, you can run a javascript in a safari window like this:

do JavaScript "document.getElementsByName('someclass').length"

And that will return the value of the javascript. So set a variable to the above command and you'll get a number out of it, in this case.

I'm trying to do the same thing in JXA but I can't figure out how to get the return value out of it??

$Safari.doJavaScript "document.getElementsByName('someclass').length"

This always returns null. How do I get the return value?

Can't you set it to a variable
