Title: LeetCode Longest Common Prefix Solution in JavaScript

Description: In this video, we'll solve the Longest Common Prefix problem on LeetCode using JavaScript. We'll go through the problem statement, discuss the approach, and implement the solution step by step. By the end of the video, you'll have a clear understanding of the problem and how to solve it.

Algorithm Description:

The Longest Common Prefix problem on LeetCode asks us to find the longest common prefix string amongst an array of strings. For example, given the input ["flower", "flow", "flight"], the output should be "fl".

To solve this problem, we can use the following approach:

1. Initialize a variable `prefix` to an empty string.
2. If the input array is empty, return `prefix`.
3. Iterate over the characters of the first string in the array using a `for` loop.
4. For each character, check if it's present in the same position of all the other strings in the array.
5. If it is, append it to `prefix`, otherwise return `prefix`.
6. Return `prefix` after the loop ends.
