"; missing before instruction" - arrays

Question

While using this code I get "; missing before instruction" error.
I believe this could have a simple explanation, but actually I can't understand what's wrong.
Also tried with switch/case statements but get same error... there could be something wrong with array...
function motori(){
var esito = [];
for (var j = 6; j < 16; j++) {
var rngRiga= foglio.getRange("AJ"+j+":BT"+j).getValues(); //store in array
var riga = rngRiga[0].join('-'); // build a string with array
Logger.log("riga = " + riga); // all right till now
if (riga.search("KOS") > -1){
var esito[j] = "KOS";} //<---- here highlights the error
else if (riga.search("OKS") > -1){
var esito[j] = "OKS";}
else if (riga.search("AN") > -1){
var esito[j] = "AN";}
else if (riga.search("OK") > -1){
var esito[j] = "OK";}
else if (riga.search("KO") > -1){
var esito[j] = "KO";}
Logger.log("result = " + esito);
Logger.log("j = " + j);
}
}
What I need is a new array with the result of the if statements.

Your issue is due to you already declared the variable esito and then inside the if you try to declare it again, so that will cause a problem because you're trying to create the same variable again. change Your code as follow:
function motori(){
var esito = [];
for (var j = 6; j < 16; j++) {
var rngRiga= foglio.getRange("AJ"+j+":BT"+j).getValues(); //store in array
var riga = rngRiga[0].join('-'); // build a string with array
Logger.log("riga = " + riga); // all right till now
if(riga.search("KOS") > -1){
esito[j] = "KOS";} //<---- here highlights the error
else if (riga.search("OKS") > -1){
esito[j] = "OKS";}
else if (riga.search("AN") > -1){
esito[j] = "AN";}
else if (riga.search("OK") > -1){
esito[j] = "OK";}
else if (riga.search("KO") > -1){
esito[j] = "KO";}
Logger.log("result = " + esito);
Logger.log("j = " + j);
}
}
