How to put javascript (page) into wordpress page


I’ve cobbled together a working javascript webpage which dispalys a map with markers on it. I don’t know javascript but I used tutorials and examples to put my page together. There is some HTML at the top and bottom of the javascript page too. That page is in my root directory and works fine. I want to display that map on a webpage in my blog. I installed WORDPRESS so I’m hoping that wordpress can handle this sort of thing. At the moment I just have a link to the map page, on my wordpress blog page, but I don’t want just a link. I want to display that map directly on a wordpress blog (or something) webpage.

EITHER that, or else I need help adding font to the javascript map page so that the map can have a legend and the javascript map page can have links to other blog pages made in wordpress.
