The Hidden Beauty of JavaScript’s findExpression Problem

In programming, we often look for the shortest path between two points. But sometimes, the journey itself is the logic.I recently worked on a puzzle: Start at 1, and reach a target number using only two operations: +4 and *2. This isn’t just a math game; it’s a perfect introduction to Recursive Backtracking. The Approach When you use recursion to solve a path finding problem, the code behaves like an explorer in a cave. It tries every left turn until it hits a dead end, then it walks back and tr
