I am learning JavaScript and what I want to do is search for keywords from a text-based website, given a URL. 

An example website would just contain text like:

```
"a" : "nice"
"b" : "nope"
"a" : "try again"
"c" : "whatever"

```

Where I'd just like to find "a" and store what it is connected to. What should I look for in JavaScript that would let me do something like this?

Another example of "text-based" website: <http://graph.facebook.com/zuck>
