Why do JavaScript functions contain a space before and after a parameter?

For example, in this video, (JavaScript Loops, Arrays and Objects: Section 2 Video 15 @6:00) there are spaces surrounding "songs" inside the function printSongs(). I'v been doing it without spaces throughout the whole track.

// How the instructor does it
function printSongs( songs )

vs

function printSongs(songs)

You've been doing it the "best practice" way already. But extra spaces are ignored by the system, and perhaps the instructor was using them just to make the name more readable.

I found what you meant in the video, but I noticed other definitions without spaces (like "print"). At one point in the video that parameter name gets highlighted, perhaps that was done to make it stand out more for that scene.
