Title
Body
var obj = {} obj.__setitem__ = function(key, value){ this[key] = value * value } obj.x = 2 // 4 obj.y = 3 // 9 JavaScript doesn't have __setitem__ and this example obviously doesn't work. In python __setitem__ works like: class CustomDict(dict): def __setitem__(self, key, value): super(CustomDict, self).__setitem__(key, value * value) d = CustomDict() d['x'] = 2 # 4 d['y'] = 3 # 9 Is it possible to implement __setitem__ behavior in JavaScript? All tricky workarounds would be helpful.
