I know there is a performance hit when calling a function vs just running the code right there but I was curious how much that would be in different browsers. I went over to one of my favorite JS testing sites, http://jsperf.com/ , and setup a simple test. Running a few tests on a few different browsers suggests that there is about a 50% performance hit when calling a function with a small task.
Testing my web development in IE is the bane of my existence. Since I run Apache and MYSQL on my local host on my Mac it was always a trick to view my work though my Windows VM until my friend Mike Farmer showed me an easy way to access my development environment on my Mac from my virtual machine.
Get default gateway of VM machine
Use that address the same way you would “localhost” on your Mac
