Learn to code your first web application
About this idea
Create a functional web app from scratch using HTML, CSS, and JavaScript. Start with a simple to-do list or calculator, then expand to more complex projects. Coding teaches logical thinking, problem-solving, and opens career opportunities. The web development community is welcoming with millions of free resources. In 20-30 hours you'll build your first app; in 2-3 months you can create portfolio-worthy projects.

Common challenges
Every beginner faces obstacles. Here's how to overcome them:
Stuck on errors, code not working, feeling frustrated
Solution: Read error messages carefully—they tell you what's wrong. Google the exact error message. Use console.log to check values. Take breaks—solutions often come when you step away. Ask on r/learnprogramming with specific error and code. Everyone gets stuck constantly—it's normal.
Overwhelmed by how much there is to learn
Solution: You don't need to learn everything—focus on HTML, CSS, JavaScript first. Ignore trends and new frameworks initially. Build projects, not tutorial hell. One technology at a time. Depth beats breadth when starting. You'll learn what you need as you build.
Tutorial makes sense but can't build on my own
Solution: You're in tutorial hell. Stop watching, start building. Rebuild tutorial project from memory without watching. Build similar project with different features. Struggle is where learning happens. Reference docs, not tutorials. Build something you want to use.
