Hey everyone! I'm currently a second-year Computer Science student and I'm looking to improve my JavaScript skills. My main programming language is C#, and I've recently gotten into Minimal API, successfully creating a CRUD web app using C# (Minimal API), SQLite, Tailwind CSS, and a bit of JavaScript for the backend interaction.
However, I often rely on AI-generated code for the frontend, which has left me feeling like I haven't truly built it myself. I ran into issues when my AI-generated JavaScript didn't work correctly with my actual data, leading to a frustrating debugging experience. Now, I want to learn JavaScript better without getting sidetracked from my ongoing C# development. What key areas of JavaScript should I focus on to be more confident in building and connecting my frontend to my backend without relying on AI or copying code? Thanks in advance for any advice!

Here are some core JavaScript concepts to focus on:
1. Use `const` and `let` for variable declarations instead of `var`.
2. Understand the difference between arrow functions and regular functions.
3. Get familiar with DOM manipulation and event handling.
4. Learn about asynchronous programming: callbacks, promises, and `async/await`.
5. Understand scope and closures.
6. Work with arrays (`.map`, `.filter`, `.reduce`) and objects.
7. Grasp the event loop and call stack.
8. Familiarize yourself with modern ES6+ features.
9. Use debugging tools like `console.log` and DevTools.
10. Aim for clean, reusable, and DRY code.
Bonus: If you're up for it, jump into TypeScript, since it's similar to C# with static typing!
Since you have a strong C# background, make sure to solidify your grasp on HTML, JavaScript, and CSS basics. It's essential to understand the DOM, and learn the difference between CSS transitions and animations. Also, modern ES6 syntax will be a must, and don't shy away from learning TypeScript—it aligns well with your experience in C#. Lastly, try to manage your own application state without overcomplicating it with heavy libraries. Stick to one framework to avoid getting overwhelmed with JavaScript's constantly evolving ecosystem.
You should definitely check out "JavaScript: The Good Parts" by Douglas Crockford. It's considered a foundational read for JavaScript programmers and helps solidify your understanding of the language. Plus, since it's focused on the best features, it won't take long to read!
Exactly! This book is crucial for anyone serious about JavaScript. It sets you up with a solid foundation before you even think about moving on to TypeScript.
If you're looking to replace your C# backend functions, consider using Node.js with Express. It could offer a smoother transition and might feel more intuitive than diving straight into frontend frameworks.
You might want to explore some online courses like those on frontendmasters.com. They've got a lot of resources that are great for learning and refining your frontend skills. Also, keep an eye out for bundles or deals on relevant learning materials, like the recent Humble Bundle offering web development books.
Totally agree! And definitely try to be okay with a bit of unstructured code since JavaScript doesn't enforce strict typing like C# does.
