Week 5 of #100DaysOfCode: Mastering JavaScript Fundamentals, Building a Blackjack Game, and My First Chrome Extension!

Reflecting on Week 5 πŸš€

This week of my #100DaysOfCode challenge was filled with milestones, challenges, and a whole lot of JavaScript! From building a simple Blackjack game to deploying a Chrome extension, I made significant progress in understanding and applying JavaScript fundamentals. Here’s a breakdown of each day and what I learned along the way.


Day 30: JavaScript Essentials for Interactive Apps πŸŽ‰

I began the week by diving into foundational JavaScript concepts:

  • Script tags and their role in embedding JavaScript.
  • Basic variables, numbers, strings, and understanding how to declare and work with them.
  • Practiced outputting data with console.log() for debugging and monitoring.
  • Explored functions and how they encapsulate logic for reuse.
  • Delved into the DOM (Document Object Model), which opened up exciting possibilities for user interaction.
  • getElementById() and innerText/textContent for selecting and manipulating HTML elements.

These skills came in handy when I decided to apply them by building a passenger counter app, a project that tested my understanding of DOM manipulation and basic JavaScript functions.


Day 31: Blackjack Game in JavaScript πŸƒ

On Day 31, I started building a Blackjack game! The focus was on if-else statements to manage the flow of the game, particularly checking win/lose conditions. Creating dynamic gameplay with conditional logic was both challenging and exciting. By structuring the game with basic rules and conditions, I gained a deeper understanding of how to manage the flow of an application.


Day 32: Working with Arrays πŸš€

JavaScript arrays were the focus on Day 32. I learned to store and manage lists of data with methods like:

  • .push() for adding elements,
  • .pop() for removing the last element,
  • .slice() for working with portions of an array.

These tools are essential, and while it took some practice, I began to see how arrays make data management efficient. Arrays are proving to be a powerful resource, and I’m excited to implement them further.


Day 33: Exploring Loops, Randomness, and Objects πŸ’»

Loops, random number generation, and objects became the highlight on Day 33. I practiced:

  • For loops for iterating over data,
  • Math.random() to generate random numbers, adding an element of unpredictability,
  • Creating and working with objects to organize data.

Each of these skills was crucial in building out the Blackjack game. The process helped me see how loops and randomness create engaging, dynamic applications, and how objects organize complex information in a manageable way.


Day 34: Blackjack Game Complete! πŸƒ

Day 34 marked the completion of my Blackjack game! The project helped me solidify concepts like conditionals, loops, and user interaction. Seeing it all come together was rewarding, and I felt an immense sense of achievement. The game isn’t just functionalβ€”it’s a representation of my growth as a developer.


Day 35: Reinforcing Fundamentals πŸ’»

Today, I dedicated time to practicing everything I’d learned throughout the week. Revisiting loops, objects, and arrays allowed me to reinforce my understanding and make my code cleaner and more efficient. Repetition is key to learning, and this day was vital in deepening my grasp on JavaScript essentials.


Day 36: Building My First Chrome Extension! πŸ”₯

I ended the week by starting a Chrome extension project. This was an exciting shift, as I learned about:

  • Event listeners to trigger actions,
  • Local storage to save data directly in the browser,
  • Template literals for creating dynamic HTML.

Seeing JavaScript come alive in real-time through an extension has been a fantastic experience. It’s shown me just how powerful JavaScript can be, and I’m thrilled to continue developing this project!


Challenges & Progress

This week, I encountered challenges with JavaScript methods, especially when working with arrays and objects. Understanding how data structures interact and using methods effectively took patience and practice. Each day, however, brought small victories, and the process of troubleshooting strengthened my problem-solving skills.
