An 8kyu should not deliberately confuse people or make them try to understand whatever happened in the author's brain when they submitted this weird description.

you are righ, same as in the original, probably ypou might want to report the issue

Missing random tests.

I don't see that test in the JS original. Maybe you know what I'm missing, I'm very new to translations.

(The NaN tests I omitted totally since there's no equivalent in Python.)

I think you missed this test case for floats:

Test.it 'should work for floats', ->
    Test.assertEquals(arr2bin([2.718281828459045,2,true]),"100.101101111110000101010001011000101000101011101101")

give me my 4 hours

yes, the root author gets credited

so, do I get points for translation?

Approved.

Forked and approved

• Resolve description MC

• Scrutinized tests

• Added useful assertion messages

• Added input and returned types

• Used assertSame instead of assertEquals to prevent loophole mentioned below

• Added corresponding headers to be compatible with PHPUnit 9.5.2

Groovy Translation

With quotes: Preserves the exact casing you provide.
Without quotes: Converts to uppercase by default.

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[]).
