Three ways to learn new technologies!

To learn new technologies, read official examples, such as JAVA pet shops or. NET pet shops. But I later understood that I cannot learn this. Because it is a stranger to new technologies, and such code is the first to become the master, the style of programming in the future will often be the same as those in these examples. In fact, we do not need to write business applications in this architecture style or show so many code modes. As a cat or a tiger, we are tired and cannot reverse our thinking. We don't need such code that looks pretty good.
To learn new technologies, the second method is to find an open-source online system. For example, some new technologies have become Forum systems or management systems. But this method also has a drawback: The Code he writes has his own style, and he is still in the trial period. He may write this thing to learn this technology, rather than developing this management system. We were a blank piece of white paper about the new technology, and he was taken to the ditch.
The third way to learn new technology is to read the source code of the new technology. It is a pity that you are not familiar with the new technology, and the source code of the new technology itself is even more complicated. You can't see the progress in the dark, and you want to give up.
Therefore, to learn new technologies, it is best to learn third-party foreign open source code based on new technologies. They understand new technologies quickly and deeply. They do not apply new technologies to try new technologies or to show new technologies. They are used to complete a practical product.
