This summer i planned to start a company. I have lots of great ideas but first I need to know a few things. One, I need to make a website. And yes I know i need HTML5 and CSS3 and JavaScript but other than that I've been wondering a few things. Like for instance. I know what javaScript is but i could never get around on how to incorporate it. I've looked at other website's source code and it always had this decently long function at the start of the HTML5 document that always confused me. I know bucky taught me the basics but its still hard for me to find the right places i want to incorporate JavaScript into.
