Secondly, you should think a lot of code logic before writing a program, instead of writing a little. Because thinking twice before you act will make your code less buggy, so quick thinking is more important than quick typing.
Actually, typing really doesn't have to be fast. Just because I like mustard doesn't mean mustard is good. I met many colleagues who typed slowly, and they were not worse than me. However, no matter how fast you type, you must be able to type fluently and blindly. One is to be smooth. We programmers hate this kind of rework when we type ten letters at a time and delete the third letter at a glance. The second is blind attack. Look at the keyboard, look at the screen, and then look at the keyboard, it will really be blind.
