Without knowledge of compilation techniques it would be ugly. But there is no need to learn a ton of compilation for an introductory example like this.
Look at something like http://www.codeproject.com/Articles/345888/How-to-write-a-simple-interpreter-in-JavaScript and see if it makes sense to you.
