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.

If you was to include jQuery and Mootools together this code below would not work:

$(document).ready(function(){
    alert("Hello World!");
});

But if we simply add jQuery(function($){ and }); then this code would work the way that we have intended.

The code would look like this:

jQuery(function($){
    $(document).ready(function(){
        alert("Hello World!");
    });
});

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.

You could store it in a variable.

or you could print it straight to the users browsers

So what happens here is if $num is greater than 0 print More than 0 else print Less than 0.

I hope you've found this quick tip helpful and use it throughout future projects.
