Is There Something Wrong With Extending Native Javascript Prototypes?

Post a Comment
I have seen some people regard extending the natives prototypes in Javascript with disdain. I was thinking about doing it, because of syntactic convenience. I.e. function(array, el

Solution 1:

It can conflict with other libraries trying to do the same.

It can conflict with future methods added to native objects.

If anyone is using for (var i in array) without proper hasOwnProperty() checks, their code may/probably will break because the new method may show up in the iteration in older browsers.
