🚀 Goal

To build a strong foundation in DSA concepts using JavaScript by:

• Watching and coding along with each YouTube video.
• Writing detailed notes and explanation for every lesson.
• Commiting regularly to this repo for consistent and progress tracking.

🛠️ Project Structure

/learn-dsa-js
├── notes/
│ └── lesson-01-intro.md
├── src/
│ └── lesson-01-intro.js
├── README.md

• notes/ - Markdown files containing summaries, insights and annotated explanations for each lesson.
• stc/ - JavaScript files with practical code snippets, solutions and experiments

🧑‍💻 Tech Stack

• JavaScript (ES6+)
• Node.js (optional for running scripts)
• Markdown for notes
• Git & GitHub for version control and transparency

📅 Learning Schedule

I aim to complete 10–20 videos per week, depending on complexity and available time. Every video will:

• Be summarized in a markdown file
• Have a corresponding code snippet (when applicable)
• Be committed with a meaningful Git message
