Turn a for loop into a static array?

Question

I am working on a backbone app, and was provided some sample code, the provider made the data into a for loop which generates a number, I don't want that. I need to enter in player names like Kobe, Lebron etc not player_1, player_2.

//generate 20 players
for(var i=1; i <= 20; i++) {
    players.add({
        id: i,
        name: 'player_' + i,
        score: Math.floor((Math.random()*20)+20)
    });
}

//generate 4 teams, and assign players to them at the same time...
for(var i=1; i <= 4; i++) {
    teams.add({
        id: i,
        name: 'team_' + i,
        players: new App.Collections.Players(players.filter(function(player) {
          return (player.id <= i*5 && player.id > (i-1)*5);
        }))
    });
}

I am not sure how I can turn this into a static piece so I can enter player names manually (name: mike, name: john) not that format of course but I dont want (name: player_1, name: player_2).

I console.logged teams.toJSON() I get the objects in the console, but I cant figure out how to get the raw JSON data so I can see how to structure a hardcoded JSON array.

That did cross my mind, but I am pretty new to javascript, and I am not sure how to create an array of names then implement it into the loop... This could have been the question itself, but I wouldn't mind writing it statically. I am open to all solutions, if you could kindly provide a sample maybe a fiddle, post it as an answer then I can award you. — Michael Joseph Aubry

names=['mike','john']; for (var i=0; i<names.length; i++) .... Same as any other language that has these basic constructs. — elclanrs

I'd suggest you take a tour of JavaScript basics here jqfundamentals.com/chapter/javascript-basics. Don't mean to sound rude, but I'm not sure how you work with Backbone without a basic understand of arrays... — elclanrs

from your comments what i understood is, you need to write

names=['mike','john'];
for(var i=0; i < names.length; i++) {
    players.add({
        id: i,
        name: 'player_' + names[i],
        score: Math.floor((Math.random()*20)+20)
    });
}

just like other languages you have to give index number to get particular element from array.
