Test output not working

JavaScript
1

I noticed that functions do not return any values even if it says ‘return ___’.
I am forced to write “Console.log()” To see any output to visually test my code.
Is this how it’s supposed to be?

The function returns the value, you are just not doing anything with it.
To see what the function returns you can wrap the function call in this: console.log(JSON.stringify( ... ))

You can also visualize your code execution with a tool like this one:
