What will this Liquid code output? 🤔 ```liquid {% assign items = "1,2,3" | split: "," %} {% for item in items %} {% assign items = "a,b" | split: "," %} {% endfor %} {{ items | join: "-" }} ```

### Explanation This is tricky because it demonstrates that: 1. Variables can be reassigned inside loops 2. The last assignment wins 3. Loop iteration doesn't create a new scope Step by step: 1. First assigns `items = ["1","2","3"]` 2. Enters loop 3. First iteration: reassigns `items = ["a","b"]` 4. Second iteration: same reassignment 5. Third iteration: same reassignment 6. After loop: `items` is still `["a","b"]` 7. Joins with "-" to output "a-b" Common misconceptions: - Thinking loop creates new scope - Expecting original array to be preserved - Thinking reassignment isn't allowed - Expecting concatenation of arrays
