A toString()’able point that allows addition
function Point(x, y) {
if (arguments.length === 1 && typeof x === 'string') {
return x.slice(1, -1)
.split('}{')
.map(function(tuple) {
return tuple.split(',', 2).map(parseFloat)
})
.reduce(function(point, coords) {
point.x += coords[0];
point.y += coords[1];
return point;
}, new Point());
}
this.x = x || 0;
this.y = y || 0;
}
Point.prototype.toString = function() {
return '{' + [this.x, this.y] + '}';
