What's parsejson syntax for parsing TA key value pair

Can someone guide on parsejson syntax at DataSet calculated field level to parse values from various keys.

I think it would be this.

parseJson({keyvalues}, “$.resourceData.curVolBurstThroughput”)

Does your JSON look exactly like that instead of

{"resourceData": {"curVolBurstThroughput": "300"}}

It’s Dictionary format. What would the best way to parse “Value” based on “keys”?
Ex. thisdict = {
“brand”: “Ford”,
“model”: “Mustang”,
“year”: 1964

Should be this

Brand =
parseJson({keyvalues}, "$.brand")

parseJson({keyvalues}, "$.model")

parseJson({keyvalues}, "$.year")
