I think Javascript environment encourages this behavior.

From day 0, a javascript project starts as a goal driven project of finishing things. Write hacky code for now we will figure them down the road. From that point on the hacks keep piling on top of hacks.

Another issue is "syntax overload". Javascript allows for doing one thing ten different way. So keep doing things your own way as long as you don't have to review other people's code. The new things JS brings out doesn't bring significant syntactical improvement and yet adds to the syntax overload syndrome.
