> For parsing desktop facebook.com, 10-15% of client-side CPU time is spent parsing JavaScript. The prototype we implemented reduced time to build the AST by 70-90%.
Whatever the win from their prototype, it should never be a reason to change core Javascript like .toString(). A facebook representative in this little proposal club doesn't feel good. My first thought was: please optimise your own codebase and don't break other people's code for your own profit.
