Create a compiler(interpreter) step by step

In order to know more about compile, I look up some video and book, after read them. I don't think understand totally. At the same time, I find a good blog. It's great example, Good job!

Thanks for Ruslans'blog.

All in the blog use Python to code. However, I prefer to use js and That's what we do now.

every part of the code interpreter can be run. example:

In chapter1

node interpreter/chapter1/part4.js "2*3*4/2"

In chapter2

npm install
npm start

1. Your can use node script like chapter1.
2. Your can also view them in browser: github.io.
