There are a number of ways to store x,y coordinates:
Option 1 (every other index in an array):
function storeCoordinate(x, y, array) {
array.push(x);
array.push(y);
}
var coords = [];
storeCoordinate(3, 5, coords);
storeCoordinate(19, 1000, coords);
storeCoordinate(-300, 4578, coords);
coords[0] == 3 // x value (even indexes)
coords[1] == 5 // y value (odd indexes)
// to loop through coordinate values
for (var i = 0; i < coords.length; i+=2) {
var x = coords[i];
var y = coords[i+1];
}
