I signed up for this course to start developing again in my mid-40s. I did some Oracle development in my 30s, but after switching to sales, I forgot about development. I was at a loss when I started again, so I decided to learn from the beginning step by step, and I am taking Dave's entire course. This is not a course for the sake of the course, but anyone who has done even a little bit of program development will know. There are separate grammars and tips that are mainly used in practice. I am studying well with the practical tests and examples. Thank you. I will finish all the back-end and front-end classes and start developing again. Even those who are learning for the first time, don't be impatient. If you look at it in the long term, the difference of 1 year, 2 years, and 5 years is nothing in the end. Please persevere to the end, and do your best. If you go all the way, you will be able to do anything, whether it is employment or self-employment, right?^^
