🚀 What I Did

• Problems on codewars.

🧠 What I Learned

Reduce()

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.

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.
