After studying vim for some time, it was not until recently that Vim's diff function was so convenient that it was no longer necessary to look for diff software or to rely on version-controlled diff in contrast to code changes.

Linux Tour (1): diff, Patch and quilt (bottom) 2 quiltOur own projects can manage all the code with CVS or SVN. But sometimes we use projects that other developers maintain. We need to change some files, but we cannot submit the code directly to the version number management tool.

The most magical part of react is the virtual DOM, and its efficient diff algorithm. This allows us to "refresh" the entire page at any time without worrying about performance issues and "without scruple", by the virtual DOM to ensure that the actual DOM operation is performed only on the truly changing parts of the interface. React is transparent enough in this section, and in real-world development we don't have to worry about how virtual DOM works.
