+The first puzzle of Advent of Code! This is also the start of the Advent of Code Hub that I created! This was a lot of work, but I'm happy to show everything I built off because I believe it will be a very valuable learning experience, not only to the people reading but to myself as well. Anyways, on to the puzzle!
+
+In this puzzle, we are on an elevator that moves up and down, and it is controlled by a series of parenthesis: `(` makes us go up and `)` makes us go down.
+
+For the first part, we need to find what floor we end up on. Single enough, I used a `.reduce()` to go through all characters and add 1 if it was a `(` and -1 if it was a `)`. For my input, my answer is `280`.
+
+For the second part, though, we need to find when we first enter the 'basement', or when we reach a negative floor. Instead of using `.reduce()`, I just looped normally and checked when we hit a negative floor. I did it with a flag, which is slightly weird, but it works...
+
+```javascript
+let floor = 0, first = -1;
+input.split('').forEach((char, index) => {
+    floor += (char == '(') ? 1 : -1;
+    if (floor < 0 && first == -1) first = index + 1;
+});
+```
+
+Afterwards, for my input, my answer is `1797`. I didn't compete during 2015 (my first was 2019), so this was done after the fact. I think for a first-ever concept, it worked well. The first part was easy while the second part used the same concept, but changed it to target a different solution.
