How long will it take me to be good at Javascript if I learn 7 hours per day?
Is it better to focus on one specific area of Javascript, like front end or back end development, or should I try to learn it all?
It depends on your interests and career goals. If you're interested in web design, focusing on front end development may be more beneficial, while if you're interested in creating web applications, back end development may be more relevant. However, having a solid understanding of both front end and back end can also be valuable in developing well-rounded skills.
