Here's how you can discover top online resources for mastering mobile app programming languages.

For fresher YouTube or crash courses form Udemy like are helpful. Like I did Flutter course by Angela Yu which was sorted by guidelines for Google Flutter official team. But for becoming a good developer on fast pace development driven learning is really important. You can feel your progress by doing project and can also use it a portfolio to crack a job .

Me ha funcionado mucho hacer uso de recursos como udemy, youtube, etc.., también, en casos especiales tenemos la documentación que es un recurso muy interactivo, como también sitios como stackoverflow.

Websites like Codecademy, Udacity, and Scrimba offer React Native coding challenges and exercises that you can write and test directly in your browser. Supporting multiple languages and skill levels, these platforms let you start with the basics and progress to complex concepts at your own pace. Instant feedback on code submissions helps you learn from mistakes and improve quickly.

Forums is one of the most accurate source of knowledge as it contains real-world problems and solutions tried and tested by many. It doesn't stop there. You can post your problems there and get solution by leading developers in the community. You can just start a normal conversation in the forum and discuss things in usual way. The benefit of forums is that you get the solution from different point of views and that's the best part of it. You can try applying multiple solutions and then find a perfect one that can work well for all scenarios. You can connect with industry experts through the forum as well. You can also provide solutions for others problems and make an impact.

Open source contributions are underrated. If you are not generating any income from the contributions doesn't mean that it's not good. It's beneficial in other ways like you can get a recgnition through your contribution in open source and land a job based on that as company leaders can know about your knowledge and methods by looking at your code. The more open source projects you have in your portfolio, the easier it is to find a new job. It's necessary to maintain a coding standard when you're contributing in open source as the codebase is modified by many other developers also. There are some open source programs that you can participate in, like google GSOC, Digital Ocean Hacktoberfest, MLH Fellowship, etc.

Official documentation is the best way to know things deeply. It's like raw food, it might be difficult to grasp in the first try, but when you start doing it, it becomes easier with time and you get to understand all of it throroughly. Although, it's not the same everywhere. Some APIs or SDKs provide really nice documentation that is easily understandable for beginners, too. When you make habit of learning to code with the help of official documentation, it puts you ahead of others in term of grasping power. You can solve complex issues and create advanced applications if you are good with understanding the documentation.

video tutorials have been incredibly helpful for learning new programming languages. For example, I once struggled with understanding a particular framework through text-based resources alone. However, when I found a well-explained video tutorial, everything started to make sense and onboard me on this issue. The combination of seeing the code written in real-time and listening to the instructor’s explanations made the learning process much smoother.
