Do update function call every frame?

I create a new javascript with the default function update.
I only do one print() in the update function, and then I attach the script to a gameobject in my game,but when run, I found the print only do once, does the update funciton called every frame?

this is my code:

function Update () 
{
	print("test");
}

Yes, as the docs clearly say, Update runs every frame. Unselect “collapse” in the console.
