If your file looks like this:

{"a":0,"b":1,"c":2,"d":3}

You basically need to parse the whole thing. Or write your own special parser.

If your file is like this:

{"a":0,"b":1,"c":2,"d":3}                                                                                 {"e":4,"f":5,"g":6,"h":7}

Then those are two separate JSON strings on adjacent lines. In which case you can read the file line by line, and each line will work with JSON.parse.
