Difference between console.log and sys.puts in node.js?

In node.js you can use console.log or sys.puts to print out to the screen.

What is the preferred method and what is the difference between these?

Answer

sys.puts simply prints the given string in the logs.

But if you want to print a more complex object (Array, JSON, JSObject) you have to use console.log because you want to “look inside” of the object.

sys.puts would give you only “[object object]” for example.
