How do i convert a sting into a variable?

Question

var activePlayer = 0;

var currentScore0 = 0;

var currentScore1 = 0 ;

var player ="currentScore"+activePlayer;

This gives me a string "currentScore0" how do I get the value from the variable currentScore0

Answer 1

You can use window["currentScore"+activePlayer] to access that variable's value but you should find a better way of storing this info so it will be easier to access it.

Here is an example of storing the info:

var players = [{
                id: 1,
                score: 0,
                active: true
              }, {
                id: 2,
                score: 0,
                active: false
              }, getPlayer: function(id){
                   return this.find(player => player.id == id);
              }];

Then you can do:

  var playerOneScore = players.getPlayer(1).score;

Answer 2

You could use the "eval" function.
