Check for empty value in groovyscript

[Hellotest]

In Groovy script in Ready API , trying to extract a value from Response and based on it if it null or not, need to write next few steps.

But value which is returning is [].

Then if I check with null or "" it does not work .

How do I check if value is [].

Please suggest

You are getting JSON Array in response with no elements in ti.

So, you can check the size is zero or not.
