Can't access JS/C# scripts in either direction.

I have two files, one is Thrusters.js, the other is FBController.cs.
Thrusters.js resides in …/Assets/_Scripts/
FBController.cs resides in …/Assets/Examples/_landerFB/

I need one of the scripts to access the other - I don’t care which way around it happens.
Hence, I try:
In Thrusters.js

var fbController : FBController;

And I get the following Error:

Assets/_Scripts/Thrusters.js(38,20): BCE0018: The name ‘FBController’ does not denote a valid type (‘not found’).

So, I try it the other way around, in FBController.cs:

public Thrusters thrusterScript;

And I get this:

Assets/Examples/_landerFB/FBController.cs(119,50): error CS0246: The type or namespace name `Thrusters’ could not be found. Are you missing a using directive or an assembly reference?

I can’t move either into Standard Assets or Plugins easily, as they’re both reliant on many other scrips and files (FBController is the Facebook Unity SDK integration for my project).

What am I missing?

If u want to access JS file in C# file

Add JS file to standard Assets folder and add both JS & C# file to same gameobject.

JavaScript file name as JSNM.

function chkval()
  print("val chk");

In C# declare as

public class CSharp : MonoBehaviour 
	JSNM jsfile; 	
	void Awake()
		jsfile= this.GetComponent<JS1>();

Follow the same step to access C# function in JavaScript.
