Struggling with JavaScript? Read this

So you've learned HTML and CSS, even built a simple website and now you're learning JavaScript. It's been weeks now, even several months and you barely understand a thing! I've been there.

In this article, I will show you how to learn JavaScript fast and avoid burning out before you even start.

Why you struggle with JavaScript

JavaScript can feel like a steep hill to climb, especially when compared to HTML and CSS. Here are some common reasons why you might be struggling:

1. Too much information, too fast: JavaScript has a vast ecosystem with endless tutorials, frameworks, and libraries. It’s easy to feel overwhelmed.
2. Syntax and concepts: If you’re new to programming, concepts like closures, promises, or async/await can seem like a foreign language.
3. Not enough practice: Simply watching tutorials or reading guides isn’t enough. Without practical application, the concepts won’t stick.
4. Skipping the basics: Diving into advanced topics without a solid foundation can leave you confused and frustrated.

The right approach

If you want to learn JavaScript effectively, you need a structured approach that prioritizes practice and builds your confidence step by step. Here’s what works:

1. Master the fundamentals: Focus on understanding variables, data types, loops, functions, and conditional statements before moving to advanced topics.
2. Learn incrementally: Tackle one concept at a time. Don’t jump into frameworks or libraries before you’re comfortable with vanilla JavaScript.
3. Practice, practice, practice: Write code every day. Solve small problems, build simple projects, and review your solutions.
4. Test your understanding: Use test cases to validate your code. This not only improves your problem-solving skills but also prepares you for real-world scenarios.
5. Work on projects: Build practical and challenging applications that integrate multiple concepts. Projects give you a sense of achievement and look great on your portfolio.

Suggested roadmap

Here’s a four-week roadmap to mastering JavaScript:

Week 1: Fundamentals

• Learn about variables, data types, and operators.
• Practice using loops and conditional statements.
• Write functions and understand scope.
• Suggested exercise: Write a function to check if a number is prime.

Week 2: ES6+ Features

• Learn about let/const, template literals, and arrow functions.
• Understand destructuring, spread/rest operators, and modules.
• Get comfortable with promises and async/await.
• Suggested exercise: Write a function to fetch data from an API using async/await.

Week 3: Arrays, Objects, and Text

• Master array methods like map, filter, and reduce.
• Work with objects: create, update, and loop through them.
• Practice string manipulation techniques.
• Suggested exercise: Create a function to count the occurrences of each word in a string.

Week 4: Build Projects

• Consolidate your knowledge by building real-world projects:
  • A to-do list app.
  • A scientific calculator.
  • A simple weather app using an API.
• Use test cases to validate your code.
• Suggested exercise: Build a scientific calculator that uses all the math functions you’ve learned.
