I need help to change C# to JS

Hello! To see if they can help me because they never answer my questions !!!

Well, what I need to do is to change the language of this code that I enter in the language of “Javascript” since at the moment I only specialize in that code.

Hope someone can help me…

using UnityEngine;

public class TEST: MonoBehaviour {
	void OnGUI() {
		
		GUILayout.Label("Score: " + score.ToString());
		GUILayout.Label("Best Score: " + bestScore.ToString());
		
	}
	public int score {
		get;
		private set;
	}
	
	public int bestScore {
		get;
		private set;
	}
	
	private Vector3 startPosition;
	
	void Awake() {
		
		startPosition = transform.position;
		bestScore = bestScore;
	}
	
	void Update() {
		
		score = Mathf.RoundToInt(Mathf.Abs(transform.position.x - startPosition.x));
		bestScore = Mathf.Max(score, bestScore);
	}
	
	public void OnGameOver() {
		
		transform.position = startPosition;
	}
}

Help please!!
