Using an array through a switch() statement in Javascript

Question

I\'m trying to develop a simplified poker game through Javascript. I\'ve listed all possible card combinations a given player might have in its hand ordered by its value, li

Answer 1

You can try switching on a textual representation of the array.

switch(sortedHand.join(' '))
{           
    //Pair
    case '1 1 4 3 2': sortedHand.push(1,"Pair"); break;
    case '1 1 5 3 2': sortedHand.push(2,"Pair"); break; 
    case '1 1 5 4 2': sortedHand.push(3,"Pair"); break;
    case '1 1 5 4 3': sortedHand.push(4,"Pair"); break;
    // etc.
}

As an alternative to specifying every case directly, perhaps build a function dispatch table using an object and get rid of the switch entirely.

var dispatch = {};

// Build the table however you'd like, for your application
for (var i = 0; i < 10; i++) {
    (function(i) {
        var hand = ...; // Add your hand logic here
        dispatch[hand] = function() { sortedHand.push(i, "Pair"); };
    })(i);
}

// Execute your routine
dispatch[sortedHand.join(' ')]();
