I have a JSON response with around 10,000 responses in it all in this particular format

```
{"SessionName": "rdp-tcp", "userid": "TEST:3:09-48-16-04-48-00", "ComputerName": "SERVER1", "LogonTime": "2016-08-09T04:48:00"}

```

I would like to be able to pull out the responses that fit a certain criteria based on a match of a partial response

For example what i am trying to get is all the Logons that occured during 4am-5am

This could be achieved by being able to query on the following:

```
"LogonTime": "2016-08-09T04:48:00"

```

How can I with (for example with Javascript) match against a partial or startswith style query in JSON to pull out all responses that fit a particular chunk of text?

Thanks in advance!
