Now that we’ve covered the basics of binary trees in our first post, it's time to dive into traversals—the key concept that allows us to visit each node in a tree. Traversing a binary tree is one of the most fundamental operations you'll need when working with trees in real-world applications. In this post, we’ll break down Depth-First Search (DFS) and Breadth-First Search (BFS) tree traversal algorithms, explain how they work, and show you how to implement them in JavaScript.
