Каковы мои опции для работы со скидкой с цены в ColdFusion?

Рекурсивный & amp; работает на NESTED массивах:

function ArrEQ(a1,a2){
   return( 
        //:Are both elements arrays?
        Array.isArray(a1)&&Array.isArray(a2) 
        ?
        //:Yes: Test each entry for equality:
        a1.every((v,i)=>(ArrEQ(v,a2[i])))
        :
        //:No: Simple Comparison:
        (a1===a2)
   );;
};;

console.log( "Works With Nested Arrays:" );
console.log( ArrEQ( 
    [1,2,3,[4,5,[6,"SAME/IDENTICAL"]]],
    [1,2,3,[4,5,[6,"SAME/IDENTICAL"]]]
));;     
console.log( ArrEQ( 
    [1,2,3,[4,5,[6,"DIFFERENT:APPLES" ]]],
    [1,2,3,[4,5,[6,"DIFFERENT:ORANGES"]]]
));;
