Sample input:

JSONArray_pop( "[ 1, 2, 3, 4 ]" )

Sample output:

"[ 1, 2, 3 ]"

Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

//Expects a JSON Array
Let([
   arr = If( IsEmpty( arr ); "[]"; arr );
   arrLn = ValueCount( JSONListKeys ( arr; "" ) )
];
   JSONDeleteElement( arr; "[" & arrLn - 1 & "]" )
)

Intended to replace javascripts native Array.pop method, which removes a value from a given array and returns the value removed. In this case, we are just returning the new array with the removed value.
