Groovy Translation

With quotes: Preserves the exact casing you provide.

I don't know who you are, but let there be a divine cure upon you for creating this.

The last paragraph of the instructon is unclear

"Note2: the input data can be: boolean array, array of objects, array of string arrays, array of number arrays..."

• array of string array, array of number arrays

does that mean 2 dimensional array? but method signature param is only 1d array (object[]).

Specs are all over the place in different languages.

Error on the author's part probably or how the assertions are run

( JS )

Tests coerce results, so returning a String is actually optional.

Approved for framework update
