I use several "new" JS features, like Array.prototype.map and Array.prototype.filter. Some old browsers (namely IE<9) don't support these. If a developer is targeting these browsers as well, we can provide a shim script for them to include also. It doesn't need to be in the default code, as modern browsers all support them.
