is this better with 5 'return' elements instead of adding a variable 'winPlayer' and at the end adding something like 1 return with Player ${winPlayer} won!?

using of ternary operator is a really a game changer nowadays

So what is the value of -x be?

Never mind, I checked the question again.

I am a beginner myself so i may be wrong but i believe that {} is not needed if the function of the if statement is all on one line. if the if statement has no {}, then it will check for the code bellow or on the same line to the parameters of the if statement for the code corresponding to the if statement. This won't work if your if statement has more than one line under it.

is it javascript in if else statement, doesn't need a curly bracket?
I am a beginner of coding staff :D

Nice use of recursion. This inspires me to practice it more.

good

Thank you very much for taking the time to answer a noob's question.

That's not an array. Try console.log(invert([1, 2, 3, -4]));

This is what I passed: console.log(invert(1, 2, 3, -4));

are you sure you're passing in an array to the function?

Why does this solution give me the following error in Visual Studio?
"Uncaught TypeError: array.map is not a function"
