Recently I wrote quite a huge chunk of jQuery for a website and it worked fine. A few days later I checked back to make sure that everything was working correctly after modifying a few things, but to my surprise none of the jQuery code worked. The problem was that I had added some Mootools code, the Mootools code worked fine but the jQuery code did not. I done some searching and found that the two libraries were conflicting and all it takes is 2 extra lines of code to prevent this from happening.
I'm sure if you've been programming for a few years that you've come across when you need to check if something equals something than do something else a few times.
Well the best way to do this is like so.
Say for example we have a variable called $num and the value of it is 5.
