Homework/Practice Coding Assignment (20-min)

Part 1: Set Up a Simple Node.js Project Directory Structure

Steps:

1. Create a new directory:

   bash코드 복사mkdir my-node-project
   cd my-node-project

2. Initialize a new package.json file:

   bash코드 복사npm init -y

3. Add a script to package.json:

   json코드 복사{
     "name": "my-node-project",
     "version": "1.0.0",
     "scripts": {
       "start": "node index.js"
     }
   }

4. Create an index.js file:

   javascript코드 복사console.log('Welcome to My Node.js Project');

5. Run the project:

   bash코드 복사npm start

Part 2: Write and Save a Short Script Using REPL

Steps:

1. Open the REPL:

   bash코드 복사node

2. Write and test the following:

   javascript코드 복사// Define a multiplication function
   function multiply(a, b) {
     return a * b;
   }
   
   // Call the function
   multiply(3, 7);

3. Save the commands to a file script.js:

   javascript코드 복사const multiply = (a, b) => a * b;
   console.log('3 x 7 =', multiply(3, 7));

4. Exit the REPL and run the script:

   bash코드 복사node script.js

5. Verify the output.

Expected Outcomes

1. Students successfully set up a Node.js environment and understand how to manage versions with nvm.

2. They gain hands-on experience with the REPL and basic scripting.

3. Homework reinforces project initialization and debugging concepts.
