Here’s a 2-week study plan to learn the basics of JavaScript and Node.js. This plan assumes you’re starting from scratch and want a solid foundation in both front-end JavaScript (which is the core language) and back-end Node.js (which builds on JavaScript for server-side development).

Week 1: JavaScript Basics

In the first week, you’ll focus on learning the core concepts of JavaScript, which is essential before moving to Node.js.

Day 1: Introduction to JavaScript

What is JavaScript? Learn its role in web development.
Setting up a basic JavaScript environment (using browser developer tools, or an online IDE like Replit or CodePen).
First JavaScript program: console.log("Hello, world!");
Basic Syntax:
- Variables: let, const, var
- Data types: string, number, boolean, null, undefined, object, array

Resources:

MDN JavaScript Guide: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide

Day 2: Control Structures & Functions

Conditionals: if, else, else if, switch
Loops: for, while, do while
Functions:
- Function declaration
- Function expressions
- Arrow functions
- Parameters and return values

Day 3: Arrays & Objects

Arrays: Creation, methods (push, pop, shift, unshift, map, filter, reduce)
Objects: Creation, accessing properties, methods, for...in loops
Array and object destructuring

Resources:

Day 4: Understanding Scope & Closures

Scope: Global scope vs. local scope
Function scope vs. block scope
Closures: How closures work in JavaScript

Resources:

Day 5: Asynchronous JavaScript (Part 1)

Callbacks: Introduction to callback functions
setTimeout and setInterval: Handling timers
Error handling with try/catch

Resources:

MDN Asynchronous Programming: https://developer.mozilla.org/en-US/docs/Learn/JavaScript/Asynchronous

Day 6: Asynchronous JavaScript (Part 2)

Promises: What are promises? How do they work?
Chaining promises
Async/Await: Simplifying promise handling with async functions

Resources:

MDN Promises: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Using_promises
Async/Await Tutorial: https://javascript.info/async-await

Day 7: Review & Practice

Go over everything you’ve learned so far.
Build a small project: Create a simple calculator, a to-do list app, or a number guessing game.
Try solving problems on platforms like LeetCode, CodeWars, or HackerRank.

Week 2: Introduction to Node.js

Now that you have a good grasp of JavaScript basics, it’s time to dive into Node.js. This week will focus on setting up and using Node.js for server-side JavaScript development.

Day 8: Introduction to Node.js

What is Node.js? Understand the concept of server-side JavaScript.
Install Node.js: Download and install from nodejs.org.
Your first Node.js app: Create a simple “Hello, World!” app using console.log.
Understanding require and module.exports.

Resources:

Node.js Docs: https://nodejs.org/en/docs/

Day 9: Working with the File System

The fs module: Read and write files (fs.readFile, fs.writeFile)
The path module: Work with file and directory paths

Resources:

Node.js File System Docs: https://nodejs.org/dist/latest-v16.x/docs/api/fs.html

Day 10: HTTP Module & Building a Basic Server

The http module: Create a simple HTTP server using http.createServer().
Request and Response objects: Handle GET and POST requests.

Resources:

Node.js HTTP Docs: https://nodejs.org/dist/latest-v16.x/docs/api/http.html

Day 11: Introduction to Express.js

What is Express.js? Learn about Express as a web framework for Node.js.
Set up Express: Install via npm (npm install express).
Create a simple Express server: Set up routes and handle basic HTTP methods (GET, POST).

Resources:

Express.js Docs: https://expressjs.com/en/starter/installing.html

Day 12: Working with APIs & JSON

Handling JSON: Sending and receiving JSON in Express.
Creating RESTful routes: Basic CRUD (Create, Read, Update, Delete) operations.
Using body-parser: Parse incoming request bodies.

Resources:

Express.js Routing: https://expressjs.com/en/starter/basic-routing.html
Node.js Body Parser: https://www.npmjs.com/package/body-parser

Day 13: Databases with Node.js

Introduction to MongoDB: Setting up a simple MongoDB database.
Install and use MongoDB in a Node.js app using mongoose for object data modeling (ODM).
Basic CRUD operations with MongoDB.

Resources:

MongoDB Node.js Driver Docs: https://www.mongodb.com/docs/drivers/node/current/
Mongoose Docs: https://mongoosejs.com/docs/

Day 14: Review & Build a Simple Project

Review: Go over the key topics you’ve learned in both JavaScript and Node.js.
Build a simple project that combines everything you’ve learned. For example:
- A RESTful API with Express and MongoDB.
- A chat application using websockets (Socket.io).

General Tips:

Practice daily: Code regularly to reinforce learning.
Debugging: Use console.log() and debugging tools to understand how your code is behaving.
Community: Join JavaScript and Node.js communities on platforms like StackOverflow, Reddit, or Discord for help when stuck.

By following this plan, you should have a solid understanding of both JavaScript and Node.js by the end of 2 weeks. You can then build upon this foundation with more advanced topics!
