jq how to call function by value in variable

Question

here i defined 2 functions and call the second directly:

$ jq -n 'def f1: "here f1" ; def f2: "here f2"; f2'
"here f2"

can i define a variable and call the function name contained in the value of that variable? for example:

$ jq --arg fp f1 -n 'def f1: "here f1" ; def f2: "here f2"; "fp is \($fp)"'
"fp is f1"

I want to call the function that is defined by the fp variable. so the result would be "fp is here f1"

No. You’d have to write a dispatcher.
