# JavaScript Solution

• I don't see any JavaScript solutions here in discussion, so just put mine here:

``````var kEmptySlots = function(flowers, k) {
var theDay = -1;
var gardenSlot = [];
var days = flowers.length;
var location, verify;
gardenSlot[flowers[0] - 1] = 1;
for (var i = 1; i < days; i++) {
if (flowers[i] - 1 - k - 1 >= 0 && gardenSlot[flowers[i] - 1 - k - 1] === 1) {
location = flowers[i] - 1 - k - 1;
verify = true;
for (var j = 1; j < k + 1; j++) {
if (gardenSlot[location + j] === 1) {
verify = false;
break;
}
}
if (verify) {
return i + 1;
}
} else if (flowers[i] - 1 + k + 1 <= days - 1 && gardenSlot[flowers[i] - 1 + k + 1] === 1) {
location = flowers[i] - 1 + k + 1;
verify = true;
for (var j = 1; j < k + 1; j++) {
if (gardenSlot[location - j] === 1) {
verify = false;
break;
}
}
if (verify) {
return i + 1;
}
}
gardenSlot[flowers[i] - 1] = 1;
}
return theDay;
};
``````

It is currently the fastest solution showed in submission panel, but should not be the fastest solution, since so few people are using JavaScript.
