Coding Test Exercise - Control Jet Problem Question

A string containing a number and a "Z" separated by a space is given. You want to add numbers in a string in turn. If you get a "Z" at this point, it means subtracting the number that you just added. Given a string s consisting of a number and "Z", try completing the solution function to return the value obtained by the awkward.

My solution is to spin the iterations and put them in a new array called answer, and then subtract them when Z comes out and make answer. Use sum to solve the answer.

function solution(s) {
   let Array =s.split(" ")
   let answer=[];

   for(let i=0; i<Array.length; i++){
            answer.push(Array[i]) 
       if(Array[i]==='Z'){
            answer.pop()
        }

   }
   return answer.reduce((a,b)=>a+b,0)
}
