It is wrong, and you did not have to ask "if" it is, or even what is wrong because InDesign tells you:

If you change 'activedocument' to 'activeDocument', the script will run without errors.

for (var i = 0; i < app.activeDocument.paragraphStyles.length)

{

alert(app.activeDocument.paragraphStyles.name)

}
