This may be overly simplistic. Using this approach, you would not be able to appropriately parse things such as:

- JSON documents that have a array at the root instead of an object:

["some text", 3, { "key":"value"}]

- JSON documents that contain the "{" and "}" characters inside string values:

 { "key":"{3 + [ 4 x (1 + 1) + (5 x 2) ]}"}

- JSON documents that have objects nested inside objects:

{{ "key1": { "subKey1": "value"}},{ "key1": { "subKey1": "value"}}}

You will also come across other issues when you start dealing with JSON that was generated by other encoders. For instance, PHP encodes unicode characters in JSON strings using numerical hex codes that have to be converted into "normal" string.

Indeed! 

Note, that EasyJSON is NOT an external - it is a pure LiveCode script that you can include in your own stacks, or use with LiveCode Server.
