In this video, I solve LeetCode 100: Same Tree using a recursive depth-first traversal in JavaScript.

This problem checks whether two binary trees are identical in both structure and node values.

I break down how to compare nodes recursively and return true only if all corresponding left and right subtrees match exactly.

This is a perfect intro-level binary tree comparison problem and helps build confidence in recursion and structural thinking.

What You’ll Learn:
✅ How to compare two trees recursively
✅ Key base cases for comparing trees
✅ When to return false early
✅ Time/space complexity of the solution
