Tests:

array

for(let i = 0; i < 100; i++){
  array[i] = array[i] + 1;
  if(i == 50) break;
}

 
for(let i = 0; i < 100; i++){  array[i] = array[i] + 1;  if(i == 50) break;}

int32array

for(let i = 0; i < 100; i++){
  iarray[i] = iarray[i] + 1;
  if(i == 50) break;
}

 
for(let i = 0; i < 100; i++){  iarray[i] = iarray[i] + 1;  if(i == 50) break;}

map

for(let i = 0; i < 100; i++){
  map.set(i, map.get(i) + 1);
  if(i == 50) break;
}

 
for(let i = 0; i < 100; i++){  map.set(i, map.get(i) + 1);  if(i == 50) break;}
