- 🔗 [JavaScript for Beginners: Multidimensional Arrays + "For In" Loop (Lesson 18)](https://www.youtube.com/watch?v=ZnOAPEJGSw4)

- 🔗 [Learn 2D ARRAYS in JavaScript in 6 minutes!](https://www.youtube.com/watch?v=SmJNeJuLmVo)

### 4. 💻 Coding Progress

- 🧠 Warm-up Exercise: Implement two functions to work with 2D arrays (matrices) in JavaScript: one that transposes a matrix (swaps rows and columns), and another that calculates the sum of each row in a matrix. This challenge aims to improve your understanding of multi-dimensional array manipulation, which is crucial for various applications in data processing, image manipulation, and mathematical computations.

- 📚 **Zero to Full Stack Hero Homework**: Tailwind CSS Front End Design From Dribble

- 🦺 Project: [Project name and brief description]

```javascript

let result = [];

for (let i = 0; i < matrix1.length; i++) {

result[i] = [];

for (let j = 0; j < matrix2[0].length; j++) {

let sum = 0;

for (let k = 0; k < matrix1[0].length; k++) {

sum += matrix1[i][k] * matrix2[k][j];

}

result[i][j] = sum;
