My First Coding Project: What I Learned Building a Simple App

Hey CodeNewbie Community! 🌱

I recently completed my first coding project—a simple to-do list app—and I’m excited to share my journey! As a beginner, I was both thrilled and nervous to dive into building something from scratch. Here’s what I learned while creating this app, along with some tips for fellow newbies.

Why a To-Do List App?

I chose a to-do list because it’s a classic beginner project that covers key concepts like user input, data storage, and basic UI. I built mine using HTML, CSS, and JavaScript, as these are beginner-friendly and widely used for web development. My goal was to create a functional app where users could add, view, and delete tasks.

The Process

I started by sketching out a simple design: a text input for tasks, an “Add” button, and a list to display tasks. Here’s a snippet of the core JavaScript I used to handle adding tasks:

const taskInput = document.getElementById('taskInput');
const addButton = document.getElementById('addButton');
const taskList = document.getElementById('taskList');

addButton.addEventListener('click', () => {
  const taskText = taskInput.value;
  if (taskText) {
    const li = document.createElement('li');
    li.textContent = taskText;
    taskList.appendChild(li);
    taskInput.value = ''; // Clear input
  }
});

This code listens for a button click, grabs the input value, and adds it as a list item. It was my first time working with the DOM, and seeing my code update the webpage in real-time was a huge confidence booster!

Challenges I Faced

Understanding the DOM: At first, I struggled with how to manipulate HTML elements using JavaScript. Tutorials on MDN Web Docs helped me grasp getElementById and appendChild.

• CSS Styling: My initial design was... let’s say “minimalist” (aka messy). Learning about Flexbox made aligning elements much easier.
• Debugging: I once forgot to clear the input field after adding a task, which caused confusion. Using console.log to track values saved me hours of frustration.

Key Takeaways

• Start Small: A simple project like this taught me core concepts without overwhelming me. Break your project into tiny steps (e.g., “make the button work”).
• Google Is Your Friend: I got stuck a lot, but searching for errors led me to Stack Overflow and YouTube tutorials that explained things clearly.
• Celebrate Wins: Seeing my first task appear on the screen felt like magic! Celebrate small victories to stay motivated.
• Ask for Help: I joined a CodeNewbie Twitter chat (#codenewbie, Wednesdays at 9 PM EST) and got tips from others that improved my code.

What’s Next?

I’m now adding features like a “delete” button and saving tasks to local storage so they persist after a page refresh. I’m also exploring frameworks like React to make my app more dynamic.

What was your first coding project, and what did you learn from it? Any tips for making a to-do list app even better? I’d love to hear from the community!
