What are the core components online instant messaging? Such as Facebook IM?

Are there any resources that walk you through the process?

I would say learning AJAX is a good place to start. NodeJS and Javascript frameworks like AngularJS and EmberJS are also very cool tools that could suit pretty well to create that functionality. I'm not sure what Facebook uses for their specific case though.

I understand. So would there be a need for any PHP or MySQL? Thank you for your answer.

Yes, most likely. In order for me to send you a message (or even post this comment), the message needs to be sent off to a server, stored in database and sent back to the appropriate client (your computer). So you'll need to be able to write server-side code like PHP, and manipulate data in a database with something like SQL. Then again, you don't HAVE to use PHP or MySQL specifically. There are plenty of other options that have their own pros and cons.

Thank you for your response Nick.

no problem!
