After 3 years of learning JavaScript, these are the best tips for developers who are starting out
Don't give up. Staying consistent is the most important thing. At first everything feels difficult, but it's like that for most people
Searching for solutions online is not cheating. Learning from examples is fine. Copying and pasting without understanding it is cheating yourself
Master Array methods like Array.filter and Array.map well, and understand when and why to use them
Understand how the event loop works. It's a key piece for understanding performance and concurrency in JavaScript
Learn how promises work and how to use async/await to write clear and maintainable asynchronous code
Before diving into React, learn the fundamentals of Node. Knowing the backend helps you build complete applications and make better decisions
Learn to design and consume REST API or GraphQL endpoints. Knowing how to connect frontend and backend is crucial for real jobs
When you learn React, do it properly. Don't just stick to quick tutorials; practice by creating components, state management, and good practices
Write unit tests from the beginning. Tests allow you to refactor safely and are highly valued in professional teams
Build, build, and build. Practice is the fastest way to learn. Keep projects in private repositories while they are in progress and publish your finished projects in public repositories
Build at least ten small projects like calculators, tic-tac-toe games, or to-do lists, and at least three full-stack projects before looking for professional work
Learn to deploy your applications on AWS or other cloud services like Azure. Deployment and cloud management are in-demand skills
For databases, learn SQL before Mongo and master it. SQL is a highly undervalued but essential skill
Complete courses on platforms like Udemy are usually better than following isolated tutorials. Your learning gains structure
Your best free resource is Free Code Camp. It's unmatched for starting and practicing
The benefits of all this effort are real. The first job can be hard to get, but it's possible to learn on your own and have a successful career
Good luck. Welcome to the world of JavaScript
