About Leader Board in Javascript (Array) Help Me Please

Store you score data like this:

scores = [
    { name: "John", score: 123 },
    { name: "Joe", score: 234 }
]

If you don't have names, then use any other properties like the player index.

Then sort the data with a custom sort function:

scores.sort(compareScores);

And provide the custom sort function:

function compareScores(a, b)
{
    return a.score - b.score;
} 

You may need to swap a and b in this function if you want a different order.

Print it like this:

for (i = 0; i < scores.length; i++)
{
    name = scores[i].name;
    score = scores[i].score;
    ... do something with name and score ...
}

var score_map = {score1 : player1, score2 : player2, score3 : player3,
  score4 : player4};
var score_array = [score1,score2,score3,score4].sort();
for (var score in score_array) {
  your_output_function(score_map[score]+" - "+score);
}

Associate the scores with the player names and store the association as a javascript object. Get your hands on the scores and sort them and then iterate through the keys and use the object that had the score/player associations to print out the players and their scores.
