Using JavaScript Instead of jQuery
In Weaning Yourself Off jQUery James Halliday shows how you can use just JavaScript to easily do what you might be using jQuery–and it’s overhead as a library–to do.
As programmers build up applications up from lots of tiny components, if every component included a vendored jquery version, the total javascript size quickly baloons into multi-megabytes. When the jquery version gets pegged, version incompatibilities arise that likewise create redundancy issues. When the jquery version is left to float or its use is demanded externally in the documentation, this also does not scale well and makes it cumbersome and error-prone to use tiny pieces.
