How to reference this array

[eluser]RobertB.[/eluser]
How can get to each independent value from this array
this is a return from a json_encoded

Code:

{"empi[0][inputRO]":"Please Enter a Repair Order Number.","empi[0][writer]":"Please Select a Service Writer.","empi[0][tech]":"The Technician field is required."}

I'm trying this but no luck

Code:

console.log(response.empi);

Thanks
