This is a problem I am having for JSON parsing with JsonPath. I do come up with a solution but not sure if it is the best/only.
Suppose I have a simple JSON like this,
{
"name": "Bill",
"age" : 33
}
I need to select the "name" node if the value of "age" node is less than 40. If it is not, just return an empty array.
Could anyone share your solution? I have mine as one answer below.

First I have to use $.
to turn the JSON into an array of JSON, ie,
{
"name": "Bill",
"age" : 33
}
to
[
{
"name": "Bill",
"age" : 33
}
]
Then I can apply $[?(@.age < 40)].name
