Arrays & Objects Storing and managing data efficiently
DOM Manipulation Interacting with HTML elements
Higher-Order Functions Using map(), filter(), and reduce()
Asynchronous JavaScript Handling asynchronous operations

Key Practice Exercises:

  • Create an interactive button that changes the page background color.
  • Fetch and display data from an API (e.g., random user generator).
  • Build a simple form that validates user input before submission.

Week 3: Advanced JavaScript Concepts

Now that you're comfortable with the fundamentals, it's time to explore more advanced topics.

Progression of Learning in Week 3

Day Topic
15-16 ES6+ Features (template literals, destructuring)
17-18 Object-Oriented Programming (OOP)
19-20 Deep Dive into Asynchronous JavaScript
21 Modules and Tooling

Key Practice Exercises:

  • Create a class-based To-Do List app.
  • Build a simple weather app using an API.
  • Practice refactoring old code with ES6+ features.

Week 4: Building Projects and Practicing

Now it's time to apply everything you've learned by building real-world projects.

Suggested Projects Based on Skill Level

Project Skills Covered
