Insert data into a Javascript array #NODE ERROR( EMFILE: Too Many open files, open )

Question

I have 3 arrays in my code, INFO, INFOS AND TEST.

And I need to make a function check if the position of my test variable is equal to my info variable and if it is equal, the final variable is: In the case of the test variable in the actual code, I have 167,082 positions. In the case of the first position of the Final array:

would be: 201 - Senior military police officers

of the second: 101 - General officers of the armed forces.

and so on.

var info = ["101", "102", "103", "201"]
var infos = ["Oficiais generais das forças armadas", "Oficiais das forças armadas", "Praças das forças armadas", "Oficiais superiores da polícia militar"]
var teste = ["201", "101", "101", "201", "103", "201", "201"]

   for(i = 0;i < teste.length;i++){
     for(j = 0;j < info.length;j++){
       if(teste[i]==info[j]){
         var final=[]
         final = info[j] + " - " + infos[j]+"\n";
         console.log(final);
         fs.appendFile('resultado.json',final, function (err) {
           if (err) throw err;
         });
       } 
     }
 }

The final file always gives the following error:

EMFILE: Too Many open files, open

And It Closes Saving Only 8189 Objects.

See if that’s what you want:

var info = ["101", "102", "103", "201"];
var infos = ["Oficiais generais das forças armadas", "Oficiais das forças armadas", "Praças das forças armadas", "Oficiais superiores da polícia militar"];
var teste = ["201", "101", "101", "201", "103", "201", "201"];

function result(compare1, compare2, data) {
    var res = [];
    for(var i in compare1) {
       for (var j in compare2) {
          if (typeof compare1[i] !== 'undefined' && typeof compare2[j] !== 'undefined' && typeof data[i] !== 'undefined' && (compare1[i] == compare2[j])) {
              res.push(compare2[j] + " - " + data[i]+"\n");
          }
       }
    }
   return res;
}

 var res = result(teste, info, infos);
 console.log(res);
