Try this.

Script A

var ScriptB : ScriptB; //This should be were Script B goes

function Update () {
    ScriptB.Test();
}

Script B:

var test : int = 0;

function Test () {
    test++;
}

In this example Script A tells Script B to add 1 to the 'test' integer ever frame.

So the syntax is: "nameOfOtherScript.nameOfFunction();" ?

Spot on. With this approach it is in theory (at least) quicker than the GetComponent method, as it doesn't have too look for anything on the initial run.

what do we put after we name the variable scriptB?

 var ScriptB : What goes here?;

Use the function GetComponent() to find a script attached to a GameObject.

You can use Component.GetComponent. But it will work only if the target script is attached to your object or you need to have reference to another object to invoke GetComponent on it.
You can create static methods in your script and invoke it from anywhere .

Helle i know this post is old, but the best practice is to use "BroadcastMessage" to call a methode name on all gameobjects

Why are you proposing a new answer to a 5yr old question that's already been answered with the "best practice" answer? (to create a public reference to the other script)

Call a function in a different script, using javascript.
