An old colleague once remarked that Perl is “write-only.” That wouldn’t be funny if it wasn’t true. I think JavaScript has a similar property. Being up to my eyeballs in ExtJS lately, I have been trying to come up with ways to make my code a little more manageable. One thing any JavaScript programmer hates is variable scoping bugs. They appear all the time and take 20 hours to fix.

If you use the Extjs Dataview Example, you will notice it is does not tell you how to do horizontal scrollbars. Nor does the documentation mention this. This actually requires some trickery as this is not currently supported.
