+# Devlog - 2025-11-21
+
+## 🚀 What I Did
+
+- Problems on codewars.
+
+## 🧠 What I Learned
+
+### Reduce()
+
+```javascript
+array.reduce((accumulator, currentValue) => {
+    // logic
+}, initialValue)
+```
+
+- `accumulator` - Holds the running total or result.
+- `currentValue` - The current item in the array during the loop.
+- `initialValue` - What the accumulator starts with.
+
+```javascript
+const arr = [1, 2, 3];
+
+const sum = arr.reduce((acc, curr) => {
+  return acc + curr;
+}, 0);
+
+console.log(sum); // 6
+```
+
+- Works for numbers, strings, objects, arrays — anything.
+- Replaces many loops.
+- Very flexible.
+
+## 🔥 What's Next
+
+- Lab projects on FCC.
