Probably a problem with empty arrays

i pass these tests apart but i can not pass them together

The same error. I changed node version and it didnt helped.

I fixed my issues !
Note : Do not forget to read every details' lines xD I miss that the value in array are between 0 and 25

Select node version 8 at the top. It should give you better error messages.

On a harder tests my code runs correctly in a short time but the tests says Unspecified AssertionError and so it does not solved.
Please help.

same here

I have timeout too

Node v14 should be enabled and chai should be used in the tests.

That's because sorting wasn't stable in Node 8. Instead of sorting it twice, sort the array once.

It seems to me that some of tests is not work.
ALPHABETICALY:
{name: 'Aoey Jaws', score: 5}
{name: 'Big Bob', score: 5}
{name: 'Coey Jaws', score: 5}
{name: 'Dig Bob', score: 5}

and by the score:
{ "name": "Big Bob", "score": 70 },
{ "name": "Coey Jaws","score": 25 },
{ "name": "Dig Bob", "score": 11},
{ "name": "Aoey Jaws", "score": 5}

it works in VS but not here
