7963 :: Best way to check for Json null values?

• xioren (orginal) [2021-05-11T06:17:30+02:00] view original

  I have a situation where I recieve Json from the web and sometimes the "audio" key has a value and sometimes its "null". What would be the "proper" way to test "null"? I have:

  if $response["audio"] != "null":
    do stuff
  Run

  but this doesn't seem right.

  import json
  
  let x = parseJson("""{"audio": null}""")
  
  if x["audio"] != newJNull():
    doStuff()
  Run

  Another possible approach.

  x["audio"].kind != JNull
