Uncaught TypeError: Cannot read property '0' of undefined - Wrogrsin

I defined my variable as:

var Players = [{
    name: "personA",
    score: 50
  },
  {
    name: "personB",
    score: 50
  },
  {
    name: "personC",
    score: 50
  }
];

and the error is:

for (v=0;v<T;v++)
{
    show += "<br/>" + Players.score[v];
}

i have already defined T and show

Players.score[v]is undefined.

It should be Players[v].score.

You defined your Players variable as an array, so you have to loop over this array and not the score key.

You forgot to specify which Player. Change the code to use Players[v].score:

for (v = 0; v < T; v++) {
    show += "<br/>" + Players[v].score;
}

The Players is an array, not the score.
