regex

I am wondering what this technique is called and what it does. It seems to be validating some regular expression on the variable url. I am customizing another persons code:

var url = document.getElementById("editorURL").value;   
if(/(file|http).*/.test(url)) {

}

Maybe someone has a link to an article that explains this a bit more in-depth?
